How to Remove Admin Fields from Emails

We have Admin Fields on our variations. We would like to not have these show up on emails, since they are often blank and not necessary to show on email. When they are blank, they show on the emails anyway with commas. If there’s a filter or something we can use to remove these Admin Fields on the email, that would be great.

We do have Product Fields we want to output on the Order emails, so we don’t want to remove all meta.
