Unfortunately, I don’t believe you can force it to use CA. You can restrict which bands it uses which I’ve found to be useful in a fixed-location scenario since in my case the card & particular tower supports CA with some channels but not others so I don’t want the card to accidentally move to one of the channels that can’t support CA.
