Use DoH through AdGuard and browser at the same time?

Is there any conflicts/issues that can happen if I have DNS over HTTPS enabled in AdGuard for Windows, and in the browser settings in Firefox/Chrome at the same time? I just recently decided to try DoH through AdGuard, but I don't know if I need/should disable it in the browsers. I have them all set to the same provider, so I'm thinking it's just the same to leave them all enabled. Double protection right? Like one would be a fallback in case the other isn't working at the moment? Am I wrong?

Also what would happen if two different providers were used? I'm sure one overrides the other, and I'm thinking AdGuard would have the last say since it's at the computer level, and not a browser option. So whatever AdGuard is using is what all traffic will be routed though. Right?

Not one person understands how the DNS works? Am I posting in the wrong thread? I'll give it another day or so, and then move to Technical Support.

I think Dns over https through Adguard will have DnS Filter by adguard but doh through browser does not have that dns filter, my english is bad so hope you understand my thinking, like Internet (0) > Adguard (1) > Browser ( doh with dns filter ) but browser have build in doh seperate from system so try look up new query not from system give so (1) >" stop " > Browser > (doh no dns filter ) > display result. Turn off browser doh still result doh from adguard so using in browser just nothing but maybe give more latency
P/s: just my thought :)))
