Comment (by tom):

 As far as I can tell, the only way to bypass the proxy settings is by
 putting a policies.json file containing the relevant setting inside Tor
 Browser's data directory (on desktop) or the package directory (on
 mobile).

 Can the original poster confirm/clarify that is what they did?

 Perhaps we want to prevent this out of an abundance of caution; but if you
 can do this you can generally bypass lots of Tor Browser security
 mechanisms.
