The specs for the laptop you listed show it only supports up to 2x16GB RAM sticks, not 64 (it still might but they didn't list it, I wouldn't risk it unless you find a specsheet that confirms it can do 64 in 2x32 sticks). Also, you'd need DDR5 SODIMMS, not DDR4. You cannot use DDR4 sticks in DDR5 motherboards/laptops and vice versa, and laptop RAM sticks (SODIMM) are smaller than desktop sized DIMMs.
The CPU and SSD it comes with will be fast enough, though maybe you'll want a larger SSD if you're working with big video files. Not sure about the 4060 mobile version, it's probably enough but don't expect it to reach desktop 4060 performance.
The biggest issue I have with the laptop you listed is the screen, some models are only 45% NTSC, which is absolutely awful colour rendering. If you don't care about colour accuracy or have an external monitor that is better, that's fine. Otherwise try to find one with 72% NTSC coverage.
