Honda_Fit_17

Hi
I just bought a 2017 Honda Fit EX with 6 speed manual transmission.
I will be towing it at times behind my motorhome.
I know it can be towed and with a Push Button Start/Stop button I need to place it in Accessory mode which I know how to do.
This will unlock the steering wheel and I know it must be in Neutral and the parking brake off to start towing.

My question is...
When I do this the main dash screen stays on and I want to conserve battery power as I may be towing for hours and don't want to run down the battery to a point that it is dead or low.
What would you suggest to save battery power during this towing?

Some ideas I have is Pulling Fuse #37 (Accessories) from under dash which powers off the dash screen/radio
or
Just leave it alone and maybe it will time out and go off?
or
?

Thank you very much and looking forward to your suggestion.

John
