Does the IMX8MQ chip with kernel 5.10.72 support dual screen display?

[ximenbingmeng]

We are trying to upgrade the kernel of the IMX8MQ chip to a higher version, but we would like to confirm whether kernel 5.10.72 supports dual screen display, and what should be the effect of dual screen display?
a. The guessing effect, if the fbset command is input, should both resolutions be displayed? So how do I check the refresh rate of two screens?
b. Alternatively, if the mipi screen is a desktop system and the HDMI screen is fb0, can this be considered as achieving a different display?
c.Can Weston achieve dual framebuffer display?
d.How to open debugging information for DRM?
