If you mean supported as in someone is going to help you and fix issues for you than the answer is NO.
There was a thread in the Arduino Nano 33 IoT sub forum about converting it to Bluetooth Classic. The general principle should be the same. The description seems detailed, and some users confirmed success.

Currently range for BLE is still limited (it is a design feature of low energy focus). With BLE Long Range this may change in the future. The question is, how useful is this for the general smartphone user. I believe there are some phones that already support it, but most BLE peripherals are used within a few meters of the user. BLE LR is an optional feature in BLE 5.x.
