Quoting the documentation:
| To determine which actions apply to a request, the URL of the request
| is compared to all URL patterns in each "action file". Every time it
| matches, the list of applicable actions for the request is incrementally
| updated, using the heading of the section in which the pattern is located.
| The same is done again for tags and tag patterns later on.
| 
| If multiple applying sections set the same action differently, the last
| match wins. If not, the effects are aggregated.

Try something like:

{+block{Only Google drive XYZ is permitted}}
/

{-block}
drive.google.com/

{+block{Forbidden Google drive}}
drive.google.com/drive/

{-block}
drive.google.com/drive/folders/XYZ1234
