Yes - it's been the job of the DRAM controller for almost the entire history of computing. But that's still a part of the computer and if it stops working then your RAM will go blank in a fraction of a second

Even if it's powered, RAM will lose its data on the order of a tenth of a second. RAM doesn't just require power, it requires that your computer constantly read and rewrite it - so every 64ms your computer has to read every gigabyte of RAM and write it back.

Since i'm already running it otherwise, i've been running stuff through Home Assistant and using lovelace dashboards.

Yeah that makes sense. I can't see why there would be a vlan enabled on your local network right now as it would make lots of things not work

Can you enable multiple vlans?

The switch on its own will do nothing for you. It's only useful with a router that supports VLANs

Unfortunately in your situation you'll need to replace your current router-modem combo with a dedicated modem, a commercial router (if you don't want to build your own linux one then EdgeRouters seems pretty good value for money) and a managed switch.

If you want to keep it wired then you'll need to put it on a separate VLAN from your other devices. A VLAN effectively allows you to create separate ethernet networks over the same physical network. We use them at work to keep factory hardware separate from office hardware and I use them at home to keep a vpn open for streaming geolocked content from another country. Traffic between the two VLANs has to be routed just like it would if they were separate physical networks.

I have an Edgerouter POE which has a small built in switch and supports VLANs so I can easily dedicate a port on the switch to a particular VLAN. In my case I route that traffic through wireguard, but in your case all you really need is setting up NAT for internet access and not route it with your other VLAN.

Any commercial grade routers support VLANs, i've seen it on unifi, aruba and fortigate and have never heard of it not being supported.

As others have pointed out, if you have a switch between your TV and Router then that'll need to be a managed switch that can trunk the vlan code back to the router, otherwise all the traffic will be comingled.

Other thoughts:

You might be able to arrange your IPs to sort of fake it. If your router is 192.168.1.1 and you make the TV be 192.168.1.2. Then you could give your TV a static IP configuration and tell it that it's subnet mask is 255.255.255.252. Then it'd only consider the IPs 192.168.1.1-192.168.1.2 as being in it's local network and if it tries to access something else on the LAN then it'll send it to the router for forwarding.

I'm not sure what your router would do in that situation, but it seems unlikely it'd manage to forward that packet. You'd have to avoid putting any device on 192.168.1.3 (as that'd be the routers broadcast address) but I think you could probably make that work. It's not really secure (as anyone that compromises the TV could change the subnet) and it'd still be possible for devices on your network to send UDP packets (but not get replies from) the TV. It's also not really extendable and you probably can't get a second TV to work like that (and definitely not three), but it wouldn't require switching to commercial routers.

I like the term from Jathan Sadowski that it should be called Habsburg AI

Maybe it's a long game to well cybertrucks to people who want to own the libs, but it feels shortsighted. I seriously expected my next car to be a tesla but cant support this shit

I suppose it's strange to reach a point where I have 3 choices for gigabit and multiple much faster choices and not opt for the faster. This is literally the first time in my life that I've not had the fastest plan I can get. I can absolutely afford 10G service... But you are right, there's really no reason for it right now

Yeah, i've reached the conclusion that gigabit is enough for now. I can get 1.2, 2.5, 6 and 10 at my house but i'm staying at 1 because it's honestly plenty fast for a family of 3 - even with 2 of us working from home.

It's also not like it's a new thing. We've had Klinger in MASH, mrs. doubtfire and countless other examples that have long been a part of popular culture. Seeing bugs bunny in a dress trying to seduce Elmer didn't make me either want to be gay or trans or a furry.
