Can I create an auto-updating modpack for my friends?

I have a modpack for a server I host with my friends but they don't have a very good understanding of modding. I'm not sure how to explain it but I typically have to walk them through how to update their mods or add new ones everything our mods update.

So I was wondering if there was a Launcher like curseforge or modrinth that I can make a modpack that they can download and it'll auto update and I can add mods to that'll change on their side. We have some custom mods to so that's also something to consider.

Please help!
