TMC2209 index and diag pins

Recently got a set of 2209’s that don’t have pins soldered for the index and diag connections. I know you’re supposed to bend or remove the diag pins when using endstops, but is the index pin necessary as well? Considering the driver doesn’t come with either of them I’m trying to figure out if I need to add the index pin or just leave the driver as is. Note that the drivers will be used on an SKR Pro board and I intend to use this with dual endstop firmware.

Thanks for the assistance!

I don’t think either are necessary.

Sounds good, thank you.
