Google Domains as Dynamic DNS Updater

Nextcloud version (eg, 14):
Operating system and version (eg, NextCloudPi image on RPi):
Apache or nginx version (eg, Apache):

The issue you are facing:
I want to use Google Domains dynamic dns as I can link my domain hosted there to my dynamic dns address, which I believe I need to do in order to use let’s encrypt. Is it possible or am I only able to use duckdns etc. which seem to be built in options?

Thanks very much!
