I know I can do this through EFI Shell but what I need is to have the advance options show in BIOS.

Hi mate,
This 1st Option is here :

0x1FF19 Form: Switchable Graphics, Form ID: 0x2812 {01 86 12 28 3C 0A}
0x1FF1F Grayout If: {19 82}
0x1FF21 Variable 0x2F3 equals 0x4 {12 86 F3 02 04 00}
0x1FF27 Not {17 02}
0x1FF29 End {29 02}
0x1FF2B Setting: SG Mode Select, Variable: 0x4A2 {05 91 3E 0A 3F 0A C5 02 01 00 A2 04 10 10 02 02 00}
0x1FF3C Option: Muxless, Value: 0x2 (default) {09 07 40 0A 10 00 02}
0x1FF43 End of Options {29 02}
0x1FF45 End If {29 02}
0x1FF47 Suppress If: {0A 82}
0x1FF49 Variable 0x2F3 equals 0x4 {12 86 F3 02 04 00}
0x1FF4F Not {17 02}
0x1FF51 Variable 0x595 equals 0x0 {12 06 95 05 00 00}
0x1FF57 Or {16 02}
0x1FF59 End {29 02}
0x1FF5B Setting: PX 5.0 Mode, Variable: 0x4A3 {05 91 45 0A 46 0A C6 02 01 00 A3 04 10 10 00 01 00}
0x1FF6C Option: BACO Mode, Value: 0x0 {09 07 47 0A 00 00 00}
0x1FF73 Option: dGPU Power off, Value: 0x1 (default) {09 07 48 0A 10 00 01}
0x1FF7A End of Options {29 02}
0x1FF7C End If {29 02}
0x1FF7E End Form {29 02}

all connected !

So to change this Wecan make It in two ways :

1. Change the Control Variable 0x2F3 value to 0x04 It will show all Graphics Option
2. Change any single Graphics Variable 0x4A2 (Default 0x02 MuxLess) so It can be 0x01 too but brick !

Setting: SG Mode Select, Variable: 0x4A2 {05 91 3E 0A 3F 0A C5 02 01 00 A2 04 10 10 02 02 00}
0x1FF3C Option: Muxless, Value: 0x2 (default) {09 07 40 0A 10 00 02}

I thinks 0x01 = Muxed there ins't as HW doesn't Permit !!!
You need Schematics to check this.

Then again for all your request so for this two We will these commands :

1. setup_var 0x02F3 0x04
2. setup_var 0x04A2 0x01 (But probably switch of sceen aoutput and Black Screen)

0x1FF5B Setting: PX 5.0 Mode, Variable: 0x4A3 {05 91 45 0A 46 0A C6 02 01 00 A3 04 10 10 00 01 00}
0x1FF6C Option: BACO Mode, Value: 0x0 {09 07 47 0A 00 00 00}
0x1FF73 Option: dGPU Power off, Value: 0x1 (default) {09 07 48 0A 10 00 01}

setup_var 0x04A3 0x00

As Option: dGPU Power off, Value: 0x1 (default) {09 07 48 0A 10 00 01} is default value and You can change
I think You get Black Screen !

Then We can continue . . .
let me know
