Yes. You get can them for a decent price on Amazon. https://www.amazon.com/dp/B07XYDG7WN/ref=cm_sw_r_cp_awdb_imm_7CN99S258CT5ZR5KYBZC?_encoding=UTF8&psc=1
The goCoax units are cheaper. https://www.amazon.com/goCoax-Adapter-2-5Gbps-Ethernet-WF-803M/dp/B07XYDG7WN
If that coax run is not being used then you shouldn't have a problem.
Based on your comments about having fiber service and no TV service I cannot imagine any reason that coax run would be in use.
None of us will be answer whether or not the coax run you are considering is physically viable though. Is it cut in the middle somewhere? Is it damaged in anyway?
Yeah, MoCA should work for what you're trying to do. Consider the GoCoax unit(s) for $59 each instead https://www.amazon.com/goCoax-Adapter-2-5Gbps-Ethernet-WF-803M/dp/B07XYDG7WN
They work great and they're much more affordable :-)
Right now your coax cable is carrying 3 types of data in 3 different frequency ranges: - Live TV signals - WAN traffic from ONT to router - LAN traffic from router to other MoCA devices like your tivo boxes
If you switch your WAN connection from coax to Ethernet it has no effect on the other two types of traffic, or on your ability to later use Verizon set top boxes. If the ONT is only a few feet away then it’s very simple, see this forum post:

There’s no reason not to do this, and it gives you flexibility in possibly upgrading your plan if no change in price.
Where you may have a concern js on the MoCA LAN side. Verizon routers have MoCA LAN capabilities built in, 3rd party routers don’t but you can easily add that with a MoCA adapter like this one:
https://www.amazon.com/dp/B07XYDG7WN/
This would work fine with your tivo and any other MoCA devices. If you switch back to Verizon set top boxes, what doesn’t work is: - new set top box activation - set top box software updates
Those functions require a Verizon router.
What I would do:
Still problems? - You already own another router (your mesh system); get another node of that, get a 5-port switch and a MoCA adapter, and use that as your new router. If you ever go back to Verizon set top boxes then maybe think about going to the G3100 router
Okay, I'll get the CommScope splitter.
But are you sure it works with MoCA? The MoCA adapters I was looking at say "5 bounded channels utilize frequency 1125MHz to 1675MHz".
The Commscope splitter goes up to 1GHz (1000MHz). Doesn't this mean the signals above 1GHz would be filtered out?
