You can add a custom DNSCrypt or DNS-over-HTTPS server.

I will use AdGuard as an example.

• Please follow the link and tap "View all README.md"

• Select the appropriate server and copy sdns.

• Launch InviZible and enter the MENU.

• Enter Fast Settings.

• Tap Select DNSCrypt servers

• Tap the plus button

• Fill the fields NAME and DESCRIPTION with any text.

• Paste sdns in the appropriate field and press OK.

• Check your custom server

• Check Protect DNS with DNSCRYPT and press START.

• On the DNS tab, you can see that the custom server is working now.

You can also calculate the SDNS stamp by yourself there dnscrypt.info:
