The 2024 stuff is still available, but nothing makes you use it.
There are a couple of ways it impinges on the character sheet, but they're trivial to ignore. (Unarmed combat, and weapons having the mastery properties, which do nothing for 2014 characters.) There are also two or three basic weapons that got updated because of limitations of the site.
As above,
Id like to run a 2014 campaign w/o 2024 options or classes, does D&D beyond support this if i haven't purchased the 2024 books.
Yes.

You can use all of the 2014 content. However, there is no way to prevent 2024 character options from being available.

Also worth noting if you're planning to use the Avrae bot, that exclusively runs on 2024 rules and there's no way to access older content.
