Pressing F11 on my new Z490M-ITX/ac with i5-10400 processor at startup results in the bootable devices not being populated. I had Amazon replace the motherboard. The replacement worked flawlessly for a week, then started malfunctioning. Some EFI bootable flash drive show as they should, others now don't. To use them, I have to enter setup and change the boot order. If I just have a single SSD with Windows 10 or Linux Mint attached, the boot menu shows no bootable device. All the above is with UEFI installs and CSM disabled. If I enable CSM the boot menu works. I've tried reflashing the BIOS 1.30 and 1.20 and the Beta L1.32. It makes no difference. I tried jumpering the board. I tried different SATA cables, power supply, and many other components. The previous board a Z90M-ITX/ac never did this. I've used ASrock motherboards for years and never an issue.

I solved it myself using the free trial of https://www.easyuefi.com/index-us.html
There was a Hidden boot item in the firmware, and deleting it, fixed it. If only, I'd of known, I would not have needed to return the first one to Amazon. Sure seems like ASrock tech would of known. I wonder if thee's a way to do it in the BIOS with some key combination?

Linux users can do it with efibootmgr Show entries with this command
efibootmgr -v
To identify any that need deleted, Use blkid to compare the UUID of the EFI and delete all others.
To remove the respective boot entry:
sudo efibootmgr -b <bootnum> -B
Example:
sudo efibootmgr -b 0014 -B
