Is your feature request related to a problem? Please describe.
Permission errors constantly appear in logs when attempting operations on git remotes where access is restricted.

Describe the solution you'd like
Add ability to specify remotes to ignore/skip during git operations, preventing access attempts and error messages for those remotes.

Describe alternatives you've considered
Manually removing restricted remotes (not ideal as they're needed for reference)
