@dannyhollie frequent question. If you have a partial fibre service over a copper phone line you will require a VDSL modem but you are free to buy your own. You can use the Sky hub if you want but it does not have a modem or bridge mode so you end up with a Double NAT set up. This is less of a problem than mostbpeople think but can cause issues with some apps like corporste VPNs.
If you have a full fibre setup then your new router can be connected directly to the ONT which should work but you will need to configure it to use the correct authentication. On most lines a simple DHCPv6 PD set up works on around 20% of lines the exchange doesnt support thst so you need to use DHCPv4 Option61 which requires a log-in string of anything@skydsl|anything
Ubquiti usually support both and you maybfind axwalk through if you search the forum. Howver Ubquiti are not thst common and are quite complex to configure. Honestly to support security cameras there are far simpler alterntives. My own Deco set up offers a guest network and one for IOT kit like cameras out of the box..
Above asumescyou are in the UK and arecaware that removingbthe Sky hub means you lose the digital voice line.
