Nonprofit pricing for the Defender and Purview Suites for Business Premium

Will nonprofit pricing be available for the Defender and Purview Suites for Business Premium?   Many clients have purchased the E5 Security license when it was first released as a Business Premium upgrade, which is available as a nonprofit SKU.  A couple of months later Microsoft released the defender and purview suites for BP but never added the licenses as a nonprofit SKU.  Microsoft also removed Business Premium as an upgraded path to E5 Security (now Defender Suite).  Leaves those of us who purchased the E5 security upgrade in a bad place.  Please advise.
