Another deployment question (accommodation)

I'm extremely brand new to a HA (starting mid July) and I will be an excluded employee.

I'm wondering if there was a way to get an accommodation for deployment if I have a pre-existing issue that impacts my mobility.

I was in a bike accident and had to get 13 staples in my knee. I'm still recovering from this and can't stand or walk with any kind of endurance right now.

Are there more clerical deployment activities I can request, if it comes to that?
