Is there possibility to reset Adguard plugin to defaults on flint2?

Hi all,
Is there a possibility to reset the Adguard plugin to the default values on flint2 with 4.7.7 stock firmware without resetting the entire device? I tested the solution offered in ADguard doesn't work after add several custom DNS lists. How to reset it pleasE? - #4 by TomKatt by completely removing the configuration file, but this resulted in having to go through the entire Adguard setup process.
I ended up blocking my laptop with too restrictive settings for DNS. Currently I'm using a statically assigned IP for the DNS resolver: as it's too old to get dhcp properly.
My current settings for DNS are
client - having set the DNS resolver to the default router IP
router:
DNS Rebinding Attack Protection - true
udhcpd - all defaults
Using DNS over TLS in the moment with cloudflare as work-around
Additional questions:

1. is the default adguard plugin port 3000 accessible to unauthenticated users on the local lan?
2. is the GLDDNS system now using https ( for versions 4.7.7 and above ) for dyndns or not?

You can do this to reset AdGuard via SSH:

/etc/init.d/AdGuardHome stop
rm /etc/AdGuardHome/AdGuardHome.yaml
rm -rf /etc/AdGuardHome/data
/etc/init.d/AdGuardHome start

Then go back to your router IP and log back in and go to AdGuard http://192.168.8.1:3000

Thank you. I saw another option - reset settings in the encryption one after I did reset the unit. Your solution is a good one , but the gl customisations are lost once you remove the data.
My problem is that whenever I remove the checkbox enable plain dns , my queries get stuck.

I have the following as upstream

1.1.1.1
1.0.0.1

boostrap servers

1.1.1.1
1.0.0.1
9.9.9.10
149.112.112.10
2620:fe::10
2620:fe::fe:10

any idea what i should configure to enable dns over tls working properly on my end?
Thank you.
