Populate, match and filter parent based on populate match

[matzrm]

Hello,

I apply a match to a populate query so when the record not match it the object is null (This works great).
Now I wish to not include the parent to the result if this field is null (but the field is null only after populate). (This not works)

Do you think I can achieve this?
