Is there a way to disable One UI?

[Dave85]

is there a way to disable One UI?  I have been using Nova Launcher (happily) ever since I had my Note 4.  Now all of a sudden, every time I click the home button on my Note 8, instead of going to the home designated in Nova Launcher (which is Nova Launcher) I have to choose between Nova (one time) or One UI (always).  I would be ok with it if I had the choice of Nova (always) but it always assumes I would ever only want Nova just this one time.

Is Nova registered as the default app?

Go to settings and search 'choose default apps', scroll down and find Nova and make sure default app is selected. Then find One UI Home and uncheck the default app option.

It might be same location as it is on the S20FE, which to change default apps you need to do following.

Goto Settings
Select Apps
Select Default Apps
Select Homescreen
Select Nova

This should make Nova default launcher.

Remember to backup Nova settings as version 7 is due anytime and it's a big upgrade.
