PPP for Internet Access in iMX6ULL Colibri Module

I have designed our own carrier board which uses imx6ull module. In the same carrier board, I have SIM76004G LTE Module. I have my Linux Laptop in which I have installed ppp module and then i have connected my module to my linux laptop and commands like sudo pon fona works and an interface is listed under ifconfig. I got to know my module supports ppp.

I now want to enable ppp in my imx6ull kernel. Currently, I am using yocto project to compile my Linux Kernel. Please help us in adding support for the ppp.

What exact hardware and software versions of things are you talking about?
