Raspberry Pi 4B wifi initramfs | USB 4G(LTE) modem initramfs

Hi community!
I want to create own "Drop-Box" with Raspberry Pi 4B and Kali Linux on board.
For now I have Full disk encryption, that I can unlock via drop-bear SSH server all is fine, when I have Intertnet connection via Ethernet output, BUT What about if in some location I can not Internet connection via Ethernet, then I must use some other things wifi, or USB modem..
I can not properly configured initramfs hooks for install correct WiFi drivers for Raspberry Pi 4 with Kali Linux, I used thihs drivers and solutions "brcmfmac brcmutil cfg80211 rfkill", but nothing work, when I preconfigured some Wifi settings (I want that my Rpi4 connect to my own WiFi network with some SSID and password) in initramfs, but nothing connect and dont work... Can anybody help me in this question??
