DNS question involving Apps (especially AdGuard)

I’m running Dragonfish-24.04.2.3, and have a stupid question after installing the AdGuard app with my DHCP setting set to go through the AdGuard DNS. In Network → Global Configuration, I have my DNS set to Google’s DNS of 8.8.8.8 and 8.8.4.4 and a static IP address set as 192.168.1.2 . I’m assuming that all of the Apps running on TrueNAS SCALE are using the server’s DNS settings as I’m not seeing TrueNAS’s IP address 192.168.1.2 in AdGuard’s logs.

I’m 99% certain of this answer, but am I correct in that TrueNAS scale and all the installed apps are using the Network settings in Network → Global Configuration?

Did you ever sort this? I am having similar issue
