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. Use ipv4 servers every time with InviZible.

- 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.
