Questions on some MRF settings

I use MRF for system image backups once every 3 months on my 3 Windows 10 computers on a rotating basis.
I looked into their settings again and am wondering about the following:
Enable TRIM on restore
--- The computer I am doing now plus one of my other computers do not have SSD's.
--- Even though Enable TRIM on restore is the default setting without mentioning if it matters whether or not an SSD is in use, I suspect it should be unchecked: is that correct?


Then there's Restore Master Boot Record settings
Replace with the Master Boot Record from the backup (Recommended)
--- Shouldn't I uncheck that on the computer I'm doing now?
--- According to diskpart, the computer I'm doing now uses Gpt

I found answers at Restoring an image from Windows - KnowledgeBase - Macrium Reflect Knowledgebase

On the enable trim restore: "Enable TRIM on restore to increase of both the lifetime and the performance of the SSD."
--- So I'll uncheck that setting on a computer that doesn't use an SSD.
--- I know that makes sense but I just had to verify it.

On the "Replace with the Master Boot Record from the backup (Recommended)"
"Note: On modern GPT/UEFI systems this option has no effect.
To replace the Master Boot Record (MBR) with the MBR from the backup.
The MBR is a small program that executes when the computer starts up. If this program becomes corrupt then you can have problems starting the computer operating system."
--- That's fine, but if I didn't want to verify it, I wouldn't have known that in a modern GPT/UEFI system there isn't an effect.

I restored a full system image backup, not because I had to, but to test it without changes to any default settings: no problems. The subject of this thread is solved: thanks cerebus.
