Switching from Uverse to Bolt Plus minis

I currently have Uverse with 1 DVR, 2 boxes connected via coax, 1 Amazon Fire, 1Roku, 1 Google cast, an OTA antenna connected to a homeworx digital converter box that is accessible from 1 tv, and wifi internet from Uverse.

I have purchased and have in my possession 1T TiVo bolt, 2 TiVo minis, 1 MoCA filter, 1 TiVo slide pro remote.

I would like to move from Uverse to OTA plus bolt plus Fire, Roku, And Google cast using MoCA. If I can have Uverse while transitioning that would be great so that I can get comfortable with using bolt.

I have searched for instructions and I have seen everything from you can't have Uverse and TiVo to instructions I just don't understand because of the lingo.

The area I need help with is how to set up the OTA antenna (does bolt have a digital receiver so I can plug the antenna directly to the bolt?). I saw somewhere if I wanted OTA on all tvs that wouldn't work, but I didn't understand the solution. I also don't know at what point the filter is installed.

Any help with this would be appreciated. Diagrams with dumbed down lingo would help me understand too.

Thanks
