Host boot local since cannot erase after released

Hi MAAS hacks,
As topic mentioned, may I know is there anything we missed?
Is it required customise commission scripts like inject BMC texture output etc. ?
And we cannot see any related log; and boot into local drive

MAAS: 3.x
Ubuntu 20 LTS

HPE ProLiant DL360e
iLO 4

We have several models and hope to contribute MASS for further compatibility develop and test as following:

Dell: poweredge R210 II

HP ProLiant DL320e, DL360e, SL170s

And any hints for ramdisk pxe image?
