How to remove PCI interface for WiFi module on i.MX8MQ EVK

Dear All,

I would like to know how to remove the PCI interface for WiFi module installed by default on i.MX8MQ EVK.

Should I change some configurations for device tree file?

When lspci command is input, PCI information about the WiFi module basically installed is printed as follows.
