Enter BIOS when no MSI Splash Screen?

I recently enabled the ThunderboltM3 add-on card that came with my MSI Creator X299 (MS-7B96). Specifically setting the "TBT Root port Selector" to "Auto Detect" from the default of "Disabled". This change also forced several other changes including enabling Fast Boot (plus two setting related to "Above 4G memory"). While the Thunderbolt change had the desired effect of enabling the two USB-C ports on the add-on card, it also eliminated the MSI splash screen on system boot. Is there a way to get into the BIOS setup when the MSI splash screen is disabled?

Thanks!

The Del-key works if there is a MSI splash screen displayed, which I no longer have. If I try repeatedly tapping Del-key the system just never boots, instead it displays a "Ab" code on the Debug display (SCSI Detected). I can try the Windows-based approach you mention, but it seems there should be a non-OS approach to doing this as well. Yes I can use the Clear CMOS button (or short jumpers JBAT1) to reset BIOS (eliminating the Fast Start = Enabled that I suspect is the root cause), but that seems heavy handed.

BTW, I tested the Windows Recovery approach and it does not work but rather it gets me to the non-boot situation with the Debug display showing "Ab" (SCSI Detected). I ended up Clearing the CMOS to enter the BIOS, then re-enabled the "TBT Root port Selector" (to "Auto Detect") to allow the MSI-provided ThunderboltM3 add-on card to function, enabled the USB function of the Thunderbolt card (the original motivation for all this), and finally enabled the GO2BIOS function (system boots straight to the BIOS setup by long pressing the power button about 4 seconds when the system is off). Assuming the long-press of the power button works as advertise, then I will have a way to enter the BIOS setup (without having to resort to clearing the CMOS data anytime I want to enter the BIOS setup)

FYI, enabling the GO2BIOS function also does not work for me, as it also results in a non-boot situation, with a Debug display showing "Ab" (SCSI Detected). Also when I changed the BIOS configuration (following a CMOS reset) I disabled Fast Boot, but the system is still skipping the MSI splash screen on boot. Very weird. So at this point in time only clearing the CMOS settings allows me to enter the BIOS.

When you got this AB, do you see anything on the screen?
Because AB is normally shown when computer is inside BIOS Setup.

I have a dual monitor system and both screens are blank. I see the HDMI1 monitor initially light, then is say it is going into low power mode shortly (I am assuming because there is no signal).

Try leave 1 display only and retest.
Try a different output port too if needs.

Your hunch was correct. I believe I was in the BIOS setup when the "Ab" code was on the debug display but had not video output. My issue was neither of my monitors were connected to port #1 on my NVIDIA RTX 2700 card (which has 4-ports). This was shear accident and not something I had done intentionally. So yes. tapping the DEL-key once in notice the primary monitor lighting does being me into the BIOS Setup. Thanks for the dialog and helping me run this down.
