Hello, I hope you are doing well.
That could be an option but considerer that it will generate an image for i.MX 8QuadXPlus Multisensory Enablement Kit (MEK) REV C0, corresponding device tree files, etc.
Also, you could try to create a custom board configuration with a new machine as is listed on chapter 7.2 "Creating a custom board configuration" on i.MX Yocto Project User's Guide.
Best regards.
