Per my experience, you needn’t do anything with x86 Boot Image if you are using SCCM only. Does your SCCM integrate with MDT? For MDT, it may be x86 boot image error with Windows 11 ADK.
Besides, when the ADK is upgraded to Windows 11 (10.1.22621.1), the x86 boot image is no longer useful. So, we can remove it.
Looking forward to your feedback.
