Apply config change without disconnection

Hi, I'm trying to modify config file, particularly wireless. The thing is that whenever I apply that change using the command:
/sbin/wifi
my mobile device which was originally connected to my lede temporarily lose the connection. Though it gets back, I want my device not to lose it in the middle of config file applying.
Is there any step I can take?

I think is ok to lose connection when apply that change...
Interface goes down and then up to enable that cange...
Maybe service is restarted...

Can I bypass uci by using hostapd_cli instead?
