Insyde BIOS Unlock Request: ENVY17 & HDX18

Hello to everybody. I would be really glad if somebody could help me about unlocking these HP BIOSes.

Hewlett-Packard Envy 17-2090el (LL211EA#ABZ)
- Type: Insyde Bios
- SLIC: 2.1
- RSA Signed: Yes (unfortunately)
- Link to F.1C: http://ftp.hp.com/pub/softpaq/sp59501-60000/sp59847.exe

Hewlett-Packard HDX18-1080el (FU756EA#ABZ)
- Type: Insyde Bios
- SLIC: 2.0
- RSA Signed: No (at least)
- Link to F.21: http://ftp.hp.com/pub/softpaq/sp42501-43000/sp42951.exe
- Link to F.34: http://ftp.hp.com/pub/softpaq/sp51501-52000/sp51618.exe
(I prefer use F.21 for my multiboot XP-7-Linux OS installation but last revision is F.34, so I putted both because I don't know if F.34 is really more stable than F.21).

For both my question is if it is possible to unlock everything has been hidden from the end-user, especially AHCI/RAID configuration, memory clock/timings, graphics features, power settings, and if BIOS can, the rest.

If I forgot something, please tell me what is missing, and I will add accordingly.
Really, thanx a lot to anybody can help me.

I've uploaded a picture of the HDX18 initial BIOS screen.
For the Envy17 I'll upload them ASAP because it is completely disassembled for H/W Upgrade & Maintenance.

Thanx again.
