The heat vents on both side of rear hatch window has anyone covered them completely? I purchased the one piece units for each sine and the have an adhesive to hold them in place are they mention to stay in all the time or only for pressure washing

I don't think they are just for styling .
The vents in front of the rear wheels on a C8 Corvette serve the purpose of relieving built-up air pressure inside the wheel arches. This helps reduce aerodynamic lift and provides extra stability at performance driving speeds. Additionally, some vents on the C8, especially on higher performance versions like the ZR1, are designed to cool components such as brakes or transmission oil, enhancing thermal management and maintaining peak performance. These vents are not just for show but have key aerodynamic and cooling functions.
Only for people that don't want water in their engine bay while washing the car.
The vents are there to cool the engine.

I would install them permanently if I had the coin. Tired of detailing my engine bay from the road debris and occasional weather I drive through...
purchase a large beach towel from Walmart.
At car wash, open rear and spread towel across the entire engine bay
Close rear opening and wash car
Remove towel after washing
easy peasy...........
And for the bottom glass open area, Cut and fit a piece of foam pipe insulation

Made thick cardboard inserts to size & wrapped them in fiber tape to fit in all 6 vents, cover engine with towel and block bottom glass opening. Wash at home only! Not everyone’s solution but works perfectly leaving a dry engine bay.
I like the towel idea, might try that. Hope I remember to remove the towel afterwards lol.
I would advise against blocking the engine vents permanently, they are there for a reason. Too much heat isn't going to make the engine perform any better...

Clean it afterwards. Get a cleaning wand from Amazon.
Geese, I wash my engine regularly.

I like to do my engine every few washes. I use Motorplast and give the big parts a wipe and looks fantastic.

I always foam and and wash at home.
I think people aren't sure exactly what vents and what covers you're talking about. A picture or two might help. If you're talking about the vents directly beside the rear window glass, do NOT cover those when the car is in operation. Those are very important to keep engine bay temps in the acceptable range.
