What if I disable UAC completely?
Whats the default in absence?
Last question:
Does disabling MS Defender have any impact onto the built-in firewall (rules and filtering)?

Disabling UAC can have unexpected consequences. E.g. Certain programs that depend on that approving admin access then can't function as expected. Not recommended.
