can i get suspended for simply asking to receive multiplayer modifications??

yes as its breaking the guidelines

Multiplayer modofications are mods that can ruin experience for other players.

You won’t be suspended if you use these modifcations in single player games that supports these (like skyrim, fallout4 and so on). But playing online with a mod is against the rules.

It depends what exactly you asked.

If you were asking on how to obtain or actively use multiplayer modifications to give you an actual advantage over other players, then it's against the rules and you can be suspended.

For example, if you asked "Hey, can you invite me to the modded lobby?" or "How can I download that mod menu?", then this is against the rules, as these questions imply that you are planning to use these mods.

No. But owner of servers can if you do it too much

any modification to any game especially multiplayer on the xbox live service is not allowed, unless those specific modifications are provided to you in the actual game.

and yes it is possible to get banned for asking as you are trying to modify a game or asking for the tools to do so.
