Can you configure mods in servers?

So i started a Massive Dig server today for me and my friend but there was something that was a bit annoying
we couldn't veinmine with modded tools we know how to fix but that needs someone to get into a Config file of veinminer and edit it
to use all tools and break all blocks within the modpack is that possible with Aternos?
-sorry for my bad english-

wow that was a fast reply xD
thanks anyway
Veinminer can still work with vanilla tools
not much of a problem
