How to link my Google Domain to a custom HTML webpage
My team and I have recently purchased a Google Domain, but when trying to have the website it is connected to, it only gives us the options of website builders. We have a GitHub repository with all of our files that we want it to host, but again, only website builders. Can I make my Google Domain connect to a custom HTML page?
Answer
You can host your content on GitHub and serve them with GitHub Pages
You can have your Google Domains domain point to it.

You'll need to add a CNAME file to your repo with your domain URL in it. Add it manually or follow the instructions here.

You'll need to add some A records at the Google Domains control panel with the IP addresses of GitHub's servers (currently 192.30.252.153 and 192.30.252.154).
