There is no vent valve. There should be a vent pipe from your black tank up thru a wall and exit on the roof with a mushroom cap. If you look on the roof directly above your black tank you should see it. There will be 2 or 3 other similar vents up there also in different areas. You should be able to remove the cap and run a snake down the pipe to the tank.

Being a 2020 I think I would be consulting my dealer to solve the problem.
