No need S-Off
What you need :
The device now on Marshmallow firmware 6.xx.xxx.x
Unlocked Bootloader
Latest TWRP
Custom ROM

I think you are confusing custom ROMs with stock (HTC) ROMs (RUU).

Custom ROMs (as mentioned): s-on if fine, just need unlocked bootloader, and custom recovery TWRP

Stock/official ROM (RUU): If you are changing carrier/region versions, you need s-off and change the CID (or SuperCID). But this is not recommended nor necessary for most folks (only suggested for experienced users, with the proper circumstances).
