Maximize BLE Range Using 1M PHY getting renegotiated to 2M PHY

My main goal is to maximize BLE range at the moment, though eventually I would like to allow for greater throughput when updating firmware over the air as well. I understand that Coded PHY is not on the roadmap based on the support ticket I previously entered, but is there any way to force 1M PHY. Even when I request it, I get a phy renegotiation (update) of 2 PHY.
