I don't understand what you are asking.
It seems to me selecting the TPM config from the boot menu could be
considered "booting into the TPM configuration" instead of selecting
the "TPM submenu". When treated as "booting into the TPM
configuration" then at the completion of configuration the next
natural step would be to reboot. This is similar to how a traditional
BIOS handles its "BIOS setup menu" - the machine reboots upon exiting
the setup menu.
I'm sure there are other ways to do this, but it does seem strange to
me to restructure the boot menu for something that I understand is
going to be very infrequently accessed.
