There is no uninstall or downgrade.

if you need to reinstall a previous OS you will need to do so by wiping the drive with Catalina first or on a blank partition. Doing this will DESTROY all data on the drive so make sure your'e backed up first.



if you don't already have a time machine backup you can reinstall the OS that shipped with your computer
