Yes. Sort of.
You a swap your ISP combined router/WiFi device by just changing the SSID and password to the exact same as the old one and all your devices will connect as they did before.
The advantage of having separate WiFi access points is that you can place them in the most efficient place to get the best coverage (E.g. in the middle of the house) instead of where bt decided to install your master socket (probably in one corner). You can also deploy multiple access points and have seamless roaming between them.
You don’t need to use the controller software, you can use use their phone app to configure the access points. If you did deploy the access point, you’d want to disable the WiFi on your isp router.
That said, if you are just placing the single Ubiquiti access point right next to your isp one, there is probably no point in the stand alone access point.
How often are you changing ISP? In reality changing the user name and password on the WiFi every 18-24 months is probably not so much of a hardship.
