vlnk - problem with the vlnk option

[Endrju]

I have a USB flash drive with Ventoy and everything is working as it should. The ISO images on the USB flash drive boot correctly. Option via F2 Boot Image Files In Local Disk also works correctly. However, I have a problem when I create a vlnk file for ISO files stored on my PC's hard drive and try to run them, a message appears



Secure Boot is enabled in the UEFI BIOS. A Ventoy USB drive created with Secure Boot and GPT enabled.
I don't know why this option isn't working for me, what's the problem?
