Aside from drying, here are some thoughts:
Double-check the print temperature, PETG should be about 240-ish. Also the spiral vase mode may be the issue if your model isn't designed for it. Also check your z offset, the first layer should be almost a flawless sheet... if not, stop the print and try again while live adjusting the z until it's correct. Typically PETG doesn't like to be squished down as much as PLA.
Update: replaced the nozzle, heat block (heating element, sensor, PTFE) and fan duct. Did two new temp towers:
Left tower is 235 (top) to 260 (layers labeled 280-260 are all 260). Right is 220-240.

I definitely feel like 220 is the right temp for this.
I’ll try the bunny again, the model is designed for vase mode, so it should work!
I had one weird roll of PETG that could only be printed at lower temperatures, so it's possible. Still looks like the filament is wet to me... I recommend picking up a Sunlu S1 Plus when it drops under $40, I like being able to both dry the spool and print straight from the dryer (only takes a couple hours to re-absorb moisture).
Dude! I just checked AliExpress for the Sunlu S1 Plus when I saw your message and was able to get one for $39 (shipped from Germany)! Thank you for that idea!
Make sure it's from one of Sunlu's official stores... aliexpressis pretty shady lol.
It is 😊 they had a coupon deal to make it that cheap
You could also mess with your retraction settings to try and reduce stringing.
