Yes in the case of Nevada it seems clear it was the players’ choice, as evidenced by their official statement. Not so much for Boise State and Wyoming who as far as I’m aware only issued vague statements. The most recent one from Boise State was particularly weird IMO, saying they “had to” forfeit. Maybe I’m reading too much into it but I also find it interesting that they did not post anything about it on their official x profile, despite multiple posts during and after their win in the previous round
