This only appears in GraphQL as you can specify which fields to return, where REST API returns all the fields and has prefetch_related for the custom-fields. Make a graphql call to any model that uses NetBoxModelFilterSet, in the debug toolbar look at the queries and see that queries are made to custom-field even though they aren't referenced in the query. Example query below:

Traced down the issue: https://github.com/netbox-community/netbox/blob/develop/netbox/netbox/filtersets.py#L249 This code is causing custom-fields to be queried even if they aren't in GraphQL request.
Found while working on issue #11291 so opening a separate bug to track.
Expected Behavior
If custom-fields are not referenced in the filter then then queries shouldn't be done for them.
Observed Behavior
Queries are always added for the custom fields.
