Samsung Magician shows SATA AHCI Deactivated. UEFI show the opposite

Hi, I have just done a new install of Windows 10 (20H2) build 19042.985. I have four NVMe SSD's , one SATA SSD and two SATA mechanical Hard Drives. My Motherboard is an Aorus Master X570. Its Users manual states that AHCI is its default.
As you can see from the attachments, my UEFI shows SATA mode as AHCI, but Samsung Magician version 6.3.0 (newly downloaded and installed) shows AHCI mode as DEACTIVATED on the SATA SSD. Its the same for the two mechanical HDDS' as well.
Searching the forum, I see that this problem was around some years ago.
Any ideas?

Did you install all the drivers on the Gigabyte disk? should auto install correct one's needed!
Just a thought...

Thank you for your reply. Yes, 7 drives and you are also correct that there are only 3 M2 sockets, but I have the 4th NVMe drive connected via a PCI-e expansion card. Incidentally, the motherboard has 6 SATA connectors, but when the third M2 socket is used, 2 of them are disabled, naturally, I haven't tried to use those two, and if I had made a mistake, I wouldn't be able to see the SATA SSD at all.
I will investigate as per your suggestions, and thanks

Once again thank you for your help.
I have visited the website for my Aorus Master X570 Motherboard and have downloaded the latest Chipset Drivers and (since it was there ) the recommended Realtek HD Audio driver. I didn’t install the AMD APU driver listed, because I don’t have an APU.
There are two other, possibly relevant drivers recommended by Gigabyte - the AMD RAID Driver and AMD RAID Preinstall Driver. They are listed on the website under SATA RAID/AHCI. But I don’t use RAID, so I assume that there is no point in installing them. What do you think?
I have also updated my BIOS from 31 to 32, the latest full (non-Beta) issue.
I have change SATA hot-swap to disabled and double-checked the SATA AHCI setting.
I have been to the Samsung website and all that the Samsung Magician page says regarding the models supported, is that all Samsung SSD are supported.
I have looked at the Samsung firmware update page that you suggested, and my SATA SSD is not listed (Samsung SSD PM871b).
I have looked at the Samsung drivers page and the only SSD ‘s listed are the 860, 870, 970 and 980 series.
I have Re-installed Samsung Magician.
None of these actions has made any difference, so I am forced to conclude that either my SATA SSD is faulty in some way, or that Samsung magician has a bug.
I am very grateful for your suggestions, even though they have not led to a fix. I am more than happy to give you a ‘rep point’, whatever that is. Please tell me how to do it.

Well Sir!!
You are clearly a genius.
The old version which looks radically different than the new shows AHCI activated. Though it shows the SSD as not supported...odd, especially since it can get all the data about it, and my 970 EVO Plus too.
Its about time someone at Samsung ran their mind over this bit of software. I speak as a retired software engineer and then manager of 30 years experience.

I am very grateful.
