EKS Anywhere cluster creation times out for RHEL8 images.

I have a RHEL8 admin machine and I have created an image from that machine to pass onto the cluster. The bootstrap cluster does get created successfully but fails to spin a real cluster. The workflow template shows "STATE_SUCCESS" status but the target machine fails to boot normally.

After tinkerbell PXEs into other machine and install OS on the disks, boot setting is changed from normal boot to UEFI. After manually changing the boot preference to normal boot, it boots from intended OS (Redhat) but the cluster creation process does not a "created successfully" message. Could you help me with this please?

Start with the bootstrap cluster and Tinkerbell PXE workflow described in the report, then inspect how the RHEL8 image is installed and how the target machine's UEFI boot setting is handled. Reproduce the timeout and compare the workflow template's STATE_SUCCESS result with the target machine's boot behavior. Done means cluster creation completes successfully without manually changing the boot preference.
