You can ask, but they are not staffed to have guests enter from the outside like they used to be.
They are staffed to get guests from the hallway that open from the Stretching Room to the boarding area.
I have not seen recent reports of people saying they were allowed to skip the stretching room area and go directly to boarding. (I'm not saying there are not any; just that I have not seen them). In the past, they did allow that for children with cognitive disabilities (for example, Autism), but I have even seen reports recently where they were told it was not possible.
Several reports recently said they were brought straight thru the first room you enter and then thru the Stretching Room as it was entering. Then they entered the hallway to the boarding area.
That might be even more problematic for some guests because of the need to move quickly in the window of time
