Have 100/100 want to upgrade 150/150. Can I use coax?

I'm scheduled to be upgraded to 150/150 from 100/100 and have been looking for the answer but haven't found a definitive answer.

I currently have the 100/100, with TiVo and a Tivo Mini. I signed up for 150/150 and would like to keep it on coax instead of ethernet, which really isn't an option. For Verizon equipment I have:

G1100 Router

GPON ONT

Also, I have a Tivo Bolt and a Tivo Mini using Moca. Will they continue to work?

Thank you.
