Bought m15 R4 (to be delivered later this month) - SSD replacement question

OK, so they m15 R4 I purchased would come with Dell's generic 512GB SSD (not Raid) and Windows 10 Home. I want to replace this SSD with my own SSD (M.2 NVMe Samsung EVO 970 512GB). Should I just replace the SSDs and execute a fresh Windows 10 install (I have a thumb drive with Windows installation ready to go) on the Samsung SSD? Or should I clone the drives? Would I lose any good stuff that was preloaded on the PC from the factory?

 

Relevant question.
Just did my SSD install on a m15 R3.
Several important considerations:

-Your actual SSD despite being a single unit, Dell generic one, it is installed with a RAID configuration at the BIOS. Nowadays it is the de facto setting no matter if it is a single unit or the kind of RAID chosen (none, 0,1,5,etc) that is specified later at the advance settings included.
Hence no AHCI and nope, the system will not identify the added SSD, unless you follow a very complex (registry modifications included) procedure according by the little information I found at DELL site.

Thankfully a very simple set up procedure is available on youtube (the millennial way) so if you simply belong to that group, then you would have solved it fast. If you are GenX or prefer to follow tech places you may loose a lot of time an perform risky operations on your laptop...
Basically, you F2 your way into the BIOS, replace the RAID setting for the AHCI one AND carefully restart into safe mode once*. That's it! Next start the new SSD will be visible for Windows and if it is not appearing there, the Disc Management utility will do it.

*The thing is that restarting into F8 safe mode seems to be a bit elusive, so there is a registry change (an later revert) that could be applied, and that is what the video describes:


Finally go to "Disc Management", the added SSD should appear there (otherwise rinse and repeat) and with it create the partitions, remember to leave unallocated between 10 to 15% of its space for good long term function.

-I left the previous Windows install untouched. It takes less than 100 GB of drive space but it will ease quite a lot of problems if your Windows has a future update problem, if you need to locate some setting, hidden file or whatever emergency. Later on when you have created other backups, when you found out you haven't lost important Dell's factory something, then you may delete that partition using the same Disk Management utility.

More so in the actual version renewal times. You'd may come to appreciate upgrading only the least mission critical Windows install into W11, and keep the other W10 untouched.
In my case I am migrating all my software and tools to the W10 install, possibly taking a degree of performance hit if we believe some reviews, but the panorama remains too liquid about the future of Windows marketing and security policies and when marketing, business and shareholders specific interests are included, these do not correlate favorably with long term wellness of professional, technical usage of budget. (iex just Yesterday is was mentioned that Control Panel is disappearing in coming versions...)

-To install the new Windows you may use the USB pendrive. Once opened it restars the laptop and then lets you choose to install into one of the new partitions you will by then have operational.
