if reboot -f -e is used, does this mean that a different BE than the
desired BE will be booted? Could we decouple -e and -f?

Is there a meaningful difference between DDI_QUIESCE and DDI_SUSPEND?
The proposed quiesce/DDI_QUIESCE says:
If cmd is set to DDI_QUIESCE, quiesce() is used to stop devices
from generating interrupts or modify or access memory.
the existing detach/DDI_SUSPEND is documented as:
If cmd is set to DDI_SUSPEND, detach() is used to suspend
all activity of a device before power is (possibly) removed
from the device. The steps associated with suspension must
include putting the underlying device into a quiescent state
so that it will not generate interrupts or modify or access
memory.
