Lock request - HP a6665it

Hello all, 
I have an unusual request...
It's possibile to remove or disable the Network adapter group from the boot order?
There aren't option to disable it, only one to disable internal network adapter.

I would disabled it because the computer won't turn on if the network cable was connected, but once you disconnect it, it will boot up, so I linked the problem to the bios order.

BIOS: AMI 5.43 (09/10/2009)
Chipset: Intel G33
Motherboard: Benicia 1.01 (https://support.hp.com/us-en/product/hp-.../c01324212)

Any help will be appreciated,
Thanks in advanced!
