Confirm with the vendor again , disable extended cmds is prevent the ESD
mechanism write (currently there is no ESD check mechanism) ic register.
So it may not have any impact whether add disable extended cmds or not.
Of course for me, I prefer to upload according to the initial code
provided by vendor.
If you prefer add it I also can fix in V6.
Thanks.
