Good idea too, now i have resolve this problem in the below service :-)

(define-public mt7921e-service-type
  (shepherd-service-type
   'mt7921e
   (lambda _
     (shepherd-service
      (documentation "关机之前运行 'rmmod mt7921e' 命令。
ThinkPad-T14-AMD 笔记本电脑使用 MEDIATEK 7961 无线网卡，所以开机的时候会自动加
载 mt7921e 内核模块，但这个模块会导致关机时间消耗很长时间(> 5分钟), 这个服务的
主要作用就是在关机之前将 mt7921 模块卸载，加快关机。")
      (provision '(mt7921e))
      (requirement '(xorg-server))
      (start #~(lambda _
                 (invoke #$(file-append kmod "/bin/modprobe") "mt7921e")
                 #t))
      (stop  #~(lambda _
                 (invoke #$(file-append kmod "/bin/rmmod") "mt7921e")
                 #f))))
   #f
