How to get rid of macOS Tahoe update?

Noticed that some of the drivers (apparently) went down due to update being self downloaded and sort of staged for install. Tried removing folders and so on, no bueno. OCLP fails "sanity check" saying

SystemVersion.plist build version mismatch 

Also, failing to find "purgePendingUpdate" app. Would be thankful for any piece of advice.
