@MacArthurHi all and @CaseySJ .
I am currently helping a friend to move from Catalina (one of your very 1st EFI 0.59 ) to Monterey OC 0.75.
He unfortunately has a Samsung 970 Nvme.
You say in your updating EFI 0.75 post:
"If Monterey is installed on Samsung NVMe SSDs, boot time can increase by 60-100 seconds due to "trim" incompatibilty.
This can be addressed by cloning the Samsung NVMe SSD to another disk, erasing the Samsung NVMe SSD with Disk Utility, and cloning macOS back. Please be careful with this process if you decide to do it."
I plan to do a clean install after reformatting the SSD and then move back Apps and so on from a TM.
Is that sufficient to prevent the trim issue and long time booting or after having do the entire restoring process I should clone again, erase the disk and clone back?
Unless you really recommend to move only to big sur 11.6.1 only...
My question may look stupid, but you know it will not be the 1st time
Thanks again your your invaluable help....
Here is another suggestion that worked for me in my Ryzen B550, and its non-destructiove if you are careful when you type the commands!!!

@CaseySJ, hi there! I just updated to 0.7.5, and everything works. I'm trying now to enable RBAR from BIOS and with -1 on the resize apple quirk in boot and -1 on the resize quirk on UEFI I can boot without problem. Here a screen of the resize bar from Windows. Unfortunately, I can't boot to...

1. Samsung 970 EVO and 970 EVO PLUS slow boot times and TRIM.
I have two 512GB 970 EVO and one 512GB 970 EVO PLUS, all of them experience the slow boot issue due to TRIM activity during the MacOS boot process. This issue appears only if the drives are formated as APFS, and it occurs in both Big Sur and Monterey. I found out that if you Overprovision the drives by 10% (Default value in Samsung Magician for Windows) the issue disapears. Because you cannot overeprovision an APFS drive in Windows, you have to do it with Disk Utility in macOS, with the following steps:
1.1 Add a new partition to your disk (not a new APFS volume) and format it as FAT32. If you decide to erase the whole disk then add the OP partition as the last one.
1.2 Note the location of the new partition in the format of diskXsX eg disk1s3
1.3 Close the Disk Utility app and open Terminal and execute the following without the quotes and by replacing the diskname with yours: "diskutil eraseVolume free free diskXsX"
1.4 You are done restart macOS and check the boot performance. If you have more than one Samsung drives the same technique needs to be applied to achieve normal boot performance.
As a note a tested the Trim performance on an empty, half-empty and almost full drive and the performance was the same.
