We are new GHL users so maybe there is a idiomatic way of doing this

We want to force the users in a specific subaccount to use their email, so when creating a an email conversation they don't have the ability to change the field

Is there a way to do it?

For example if you use mailgun and authenticate the domain, a user with email hello@domain.com could change the from to boss@domain.com, and the mail will be delivered just like that
