Yes, you can. The battery type can be set via the Bluetooth app.

It is important to set the battery type in the app.

Yes, you can use it to charge all types of batteries. Also AGM and even lithium batteries.

Theoretically, yes. But my charger has a fault: during normal charging, it brought a battery to the boil and destroyed it. When I complained to Victron Energy, I was initially told that I had selected the wrong settings, but this was not the case. Then Victron said it could only have been the battery. So I tried another battery (65 Ah, AGM). This also boiled and is now dead. Not recommended. Subterranean support from the manufacturer.
