Alright. I am hoping that you guys might be able to help me out as i have a bit of an issue.
I went back to High sierra from Mojave as mojave started to have some issues on my newly upgraded 2010 MacPro 5.1.

*******************
As you can see, prior to go back to HS, i was hoping to get my boot rom to update to 140.0.0.0, but found out that it won't update to 140 or 142.
2 weeks after the upgrade, one of my SSD disk crapped out and bought a PCI card that can take a Crucial 1tb M2 NVME ssd drive.
I want to be able to boot to that drive instead of my Current one.
I also have a RX 580 Graphics card in running 3 monitors and a big screen.
My question to you is. Is there a way to upgrade the boot rom manually without installing Mojave as 10.14.x was very unstable on my macpro.
My issues with it was that one of my screen will start flickering, random screen going to sleep even though that feature was turned off and the performance wasn't there.
High Sierra is by far "in my own opinion" the most stable OS on this machine. screens doesn't flicker, runs super smooth even watching 4k video.
