I don't see why you wouldn't. Unless its important to you to see her walk across the stage.
I will say that I had a horrific high school experience and left high school early, I did return to walk and it was OK. I did it more for my parents than anything. My youngest also had a horrific high school experience and didn't attend their Senior year either (we both started college classes early) - and did walk. It wasn't THAT important for either of us individually, but it made parents and grandparents happy. Plus, there was something final about the ritual - because we both hadn't been in the building in months.
But it sounds like your daughter has some high school related trauma. Let her get out out walking (and honestly, get her out of high school early if you can - it might be late to enroll in a community college, but if you can do something - online school if it worked during Covid? you might, high school can be traumatic for those that don't fit in).
I think its particularly tough for the Covid kids. If they were isolated before Covid, Covid didn't help - and it illustrated what a farce the "going to high school" part of getting an education actually can be.
May she find her people in her next stage.
