Is this still possible? None of my pcs boot off of a usb stick and the
cdrom I think is failing on one of them, so I really need to install from
the disk. Any suggestions? Thanks!
Much simpler to just do an inplace upgrade using dnf system upgrade.

Otherwise you're kinda in GRUB hacking territory. You could copy the
contents of the installer ISO to a spare ext4 volume, and then when
you reboot use ls to find that partition's desigation, then something
like
configfile (hd0,msdos5)/EFI/BOOT/grub.cfg
That'd load the UEFI grub.cfg. Sounds like you have traditional BIOS
firmware, so you'd need to select the first boot entry, then hit 'e'
to edit, and change the linuxefi to linux16 and initrdefi to initrd16.
And then control-x or F10 to boot that modified grub.cfg. It should
work. *shrug* Once the kernel and initramfs are loaded, most of the
environment is setup by dracut scripts.
