Can I get my own mods onto Aternos?

Hello, I want to add my own mods that I've made from MCreator for my survival server, it'd add some armor, weapons, and some custom tweaks, my issue is that I doubt my mods will ever get popular enough on CurseForge to be accepted. There are no mods out there that give me exactly what I want so I want to add my own mods onto my server, is there anything I can do?
