Yea I've had all sorts of UniFi gear and have never seen an access point that only works on DFS channels. That'd make no sense and their admin software actively discourages DFS channel selection.
I'd guess OP might be trying to use 160mhz channel width on 5ghz band, which will only work on DFS channels though. I wouldn't recommend 160mhz channel width unless you have a very quiet RF environment and peak speed is very important to you. Also I've found it hard to get clients to actually use the full 160mhz width on a network configured this way.
