In the attached image Secure boot design is mention. As per the image, Device details are also verified. Any idea what is verified. Is it related to CSF-related details Verifications or something else?

Hello,

  Device details fuses are analyzed - as shown on the figure - during Device Details
verification. For example, i.MX8M supports HDMI, which requires signed HDMI
firmware loading, but i.MX8Mm does not have HDMI and HDMI firmware
is not needed.

Regards,
Yuri.
