Ive seen that most clients like this cant get past NoCheat+ and even if they do they are still verrryyy limited like how x-ray doesnt even really work if a server has it since all blocks look like ores so my suggestion is that you guys find a bypass for NoCheat+
Its advertised as a minecraft "Utility mod" for PvE, not a hack client or PvP, so needing to bypass anti-cheats is prob very low on the list is not zero.
