This is available in the latest release. If you're using RaspAP's 'Check for update' function on the About page, this will update the available providers and supporting code. However, this method doesn't run the installer interactively to specify your desired provider. In this event, you can enable AdGuard by executing sudo nano /etc/raspap/provider.ini and setting the following value:

providerID = 4

Save and exit this file, then refresh the web UI.
