I'm not really sure, haven't check synscan code driver in ages. If you have a patch that works for all cases, please submit an MR to INDI repo on Github.
Ok, will just do this. Please bear with me, I am quite new to this code and I have to understand it, so it may take a little time since I cannot replicate myself and there is still the workaround ...
I just created a PR, it was easier/faster than anticipated. It's not as good as I wanted because it would have made sense to disable either AltAz/EQ track mode depending on the mount type but I have not found an elegant way of doing it since I do not have good enough mastery of the API.
