Honeywell T5 and carrier performance 59TP6A, 2-stage fan operation.

Hello and thank you for the great forum. It has been very useful in multiple projects.
I have a question and reading thru the manuals and forum I could not find the answer.
Long story short,
I have a new furnace and new thermostat. I have a wood burner with a hydro coil in ductwork. I am using wood burner now for heating. My installer could not answer my question so maybe you can help.

Is it possible to operate just the furnace fan in 2-stage mode? I tried to shut off the LP but that will not work. I looked into dip switch configurations but I could not find the option from the manual.
I am looking for that fan can run all the time with the slow speed and when it gets cold and when thermostat calls for heat then the fan would go to faster mode? Right now it only works when propane is on. So same thing without the propane would be the best. Can I do this by flipping a switches from SW1 or from SW2? I would not like to add another thermostat just to control the fan.

Thanks for your help.
