Depends on what you mean by Solargraph, because it's kind of a large project. If you mean their typechecking, then definitely not, because it's not using a Ruby parser. If you mean the general feedback, then yeah potentially.

Rubocop yes if it ends up using YARP as a new backend.

Either way, I would suggest you check out ruby-lsp, which is definitely going to benefit from this speed, and soon.
