Hello Kunal Barot,
You would need to reach the manufacturer of the module to obtain a driver, as this is not included on the i.MX6UL EVK.
There are some github that contains the driver or information for this module:
https://github.com/atwilc3000/driver
And they also have a driver ready to work in Yocto. I haven’t tried integrating it to the FSL Community BSP but you may see if it’s plausible.

I hope this helps!
Regards,
