If it were me, I'd flash it with OpenWRT, cause I like tinkering with things knowing full well that I'll probably waste a day but have fun doing it.
For any sane person though, assuming it currently supports WPA3, I'd say "it's fine, leave it". If it doesn't support WPA3, I'd recommend a shiny new Unifi access point with 6GHz and Wifi 7. 💸
