I can't say for Oracle HW in general, but on T4, T5, T7 machines 
booting via DHCP/TFTP is supported, for example via 'boot net:dhcp'.

In our group we do load grub2 via dhcp/tftp. There were some issues, but 
in general this scheme works fine. I hope patches for these issues will 
be sent here soon.

Thanks.
