Changing your Name Servers in Google Domains is pretty simple. By default you will be taken to your list of domains. Select your domain and you’ll get to your DNS records using the navigation to your left.
You’ll enter your new name servers that were provided to you by your web host. Name servers typically fall into the format of subdomain1.domain.com and subdomain2.domain.com. There will always be at least two.
Be aware, it requires an additional step to change from your default settings. Be sure to click “Switch to these settings” so the appropriate settings are selected.
