    Pop!_OS uses systemd-boot bootloader by default. You can use T key and/or Shift+T key combination to change the timeout duration while the menu is on display. I have been using UKIs without a bootloader for a long time, but if I recall correctly you can reduce it to zero and have it be practically disabled.
