I disconnected the negative battery terminal to wire Baja designs A-pillar lights.
When I hooked everything back up the performance pages wouldn’t load, driving modes are blank and several other small things are different (cooling seats no longer has a medium setting, etc)

Can I fix this or should I just take it to the dealer?

I know it takes some time for some of the functionality to come back after you disconnect the battery. I would drive it around for 15-20 miles and then when in park and in the run mode, press and hold the volume and tuner knob buttons together and hold for 10-15 seconds. The screen will reset and then turn back on. Hopefully that works. If some driving and a a soft reset doesn't fix it then I'd go to the dealer.
