I reserve a browser, like brave or edge, to use when I'm on the VPN. No plugins, no password manager, plain Jane vanilla browser + VPN, so they're "fingerprinting" something I don't use. Hard to compare when literally nothing matches.
Good luck.
Plus my VPN location changes often. Sometimes I use TOR browser on VPN (not sure it helps) if I'm wading through a very gray area.
Local pihole and ublock origin (on Firefox) alone seems to make my phone "unique" on its own.
