Xiaomi MI9T injection Mode

Hello Everyone Thanks @Re4son For Your Hardworking
I have installed The Kali NetHunter Official Rom For my Device MI9T And it's really Cool I read That The Kernal doesn't Support injection mode But the external Adapter support The monitor mode and packet injection So I got a Idea in my mind
That is (Can i use The external adapter (wlan2) To connect the device To the internet And Use injection mode That supported by the external adapter To Run Man in the middle attack ? Is it possible? thanks again and iam sorry for my bad language please accept my post
