HI @subbuemdtest!
Thank you for contacting NXP Support!

To create the image using Yocto you can refer to our YOCTO PROJECT USERS GUIDE.

After that you have two options:

Configure the Kernel source using devshell 

Creating and applying a git patch in a yocto build 

Also you can consult all our documentation in our web page. 

Best Regards!
