WheelTop EDS TX Full Wireless Groupset (Chinese SRAM)

[pedalino]

Hi, I would like to use this derailleur in a 1x configuration—meaning without a front derailleur.
I have a couple of questions:
1) Is this feasible, and will the rear derailleur work correctly on its own?
2) Can the button on the left-hand lever be assigned to a different function (for example, acting as a bell, if I'm using an iGPSport BSC500)?

Thank you

Any reason why you'd prefer the EDS TX RD over the GEX RD instead since that one is made for 1x?
