Why is the SSD not showing up in UEFI without a bootable flash drive?

Installed Windows 10 from a flash drive to an SSD m2. (Options when booting the OS to a USB flash drive: NTFS, GPT). Installation goes well, installed on a clean, empty SSD. The OS starts up for the first time. If you restart the PC yourself and before that pull out the USB flash drive with the boot system, then the SSD does not even appear in UEFI (it seems that it simply does not exist) and the system does not start. As soon as you plug the USB flash drive back in, the SSD immediately starts to appear in the BIOS and the system boots stably. Help please, with what it can be connected.

Motherboard ASUS ROG Strix Gaming-e b450
SSD ADATA XPG 8100 256gb

PS: At the same time, I turned off the HDD so that it would not interfere with the installation and would not share SATA ports.

It seems that you have not created a boot partition on the disk.
I would try to run the system installation again, delete all partitions in the disk selection window (all information will be lost), select "Unallocated area" and click "Next" to start the installation.
If you can at the same time make a flash drive "read-only" - perfect.
All other drives should be disabled for the duration of the installation.

On Asus, there is such a feature, in the priority of disks, it can offer loading only from the disk that is selected as the main one and boot options - it offers only on it, the rest bypasses.
First, take a close look at your SSD (yes, at least in the same Windows installer) - are there any UEFI partitions there? If there is - kick the motherboard so that it would prefer a drive with an SSD.
If not, look for where it's gone, maybe the second number in the computer is hard and the installer "modified" it?
