How to add mt7601u driver in android kernel 3.18.140?

I have rooted Redmi 4x (santoni) with installed Lineage-14.1 (Nougat, kernel is 3.18.140-Loup) and mediatek mt7601u wifi adapter. Last week was spent to connect this adapter to use with Nethunter, but I still have no success. The kernel source doesn't contain driver for this adapter. There is working kernel with the driver, but it's made for android 11 and 10 (installing on android 7 causes bootloop). I don't want to change my ROM. I tried using driver from the linked kernel and from the linux repository, but they are incompatible with my kernel (compilation terminated). I also tried compiling kernel module from the repository . This module does nothing, no matter if there is firmware in /etc/wireless. Expected: new wireless interface ra0 or wlan1 after connecting the device via OTG. Reality: only power supply and some strings about the device in dmesg(pid, vid, manufacturer, etc).
