Why isn’t [Launch CSM] function in the BIOS setup menu?

The Windows Operating System which supports Intel CoffeeLake and later processors is limited to Windows 10.

So [Launch CSM] feature(option) is no longer in the BIOS Setup menu from Intel CoffeeLake processors.

If the media cannot boot, disable quick boot and try again. If it still does not, try making a new one. Make sure the disk layout is set according to what it is right now(modern devices are based on GPT) and partition scheme is set to UEFI.

you can install easily, by disabling secure boot in bios.

make sure your USB pen drive must be formatted as NTFS and partition type as GPT for UEFI (non-csm).

Use  Rufus 3.9 software to make bootable, i am also using ASUS vivobook R542UQ

Your USB drive is either made incorrectly or is bad.

Use Rufus for the same - option 2 explains better:
