Not specifically, no. You can search the ATT Dev section for 5.0 ROM as easily as I can. Or if you don't need or want an ATT based ROM, you can also look in the "international" Dev section: https://forum.xda-developers.com/htc-one-m8/development
Also, ROMs which have been updated (Android 6, 7) may or may not still have links to 5.0 versions.
Alternately (and probably easier to find) just restore a stock TWRP backup of a 5.0 ROM: https://forum.xda-developers.com/htc...-twrp-t3086860
You don't need (or want) to restore the data partition, so it is essentially the same as flashing a ROM (although getting the files to the right location is a bit trickier). Also, no need to install stock recovery (as getting an OTA update is not
what you want). Then root if desired.
