Magento2 collection filter two different values for same attribute as AND search instead of OR

I have some multi-select product attributes that need to be filtered with an AND instead of OR.

In other words a product needs to have an entry for an attribute for the first marked value AND the same product must also have an entry for the other value.

I found options such as FINSET, using consecutive filters for the same category in the same loop, but none will filter the way I need.

None of the questions I found on the site related to this had a response that works.

Help ! Thanks !
