Is it possible to have just a single selection?

Good Day all! I hope all is well or at least getting better.

I generally man just support roles, I am not very good with other roles and tend to die more if I play those roles. And with the community can be as it is sometimes I am even more hesitant to try out something different out of fear of how people will react to it. So my question is even if we had to wait longer, could we get to choose just 1 role? Like I only want to be support, I have no desire to do anything else. Of course there should be an option to continue as normal, but for those of us willing to wait single role selection should be possible.
