Install software update using mobile data instead of wifi??

[almostfamousjh]

I have the Galaxy j3 Luna pro, I tried to install a software update by clicking software update in the settings, it says there is an update available, to connect charger and connect to WiFi to complete update. However, I do not have wifi and not able to travel an area where I can connect to a public WiFi, is there any other way to install the software update? I can't find a setting to use mobile data instead of wifi. Please help me if possible.
