GalliumOS on Acer Chromebook 315

Hello, does anybody have any experience TOTALLY wiping an Acer Chromebook 315 with an Intel cpu and installing GalliumOS? I can get the Chromebook cheap but I don't want to use "Crouton" to dual boot but totally wipe the ChromeOS off the eMMC drive. GalliumOS is optimized for Chromebooks according to them. Or I could use Ubuntu 20.04. There are tutorials online but most of them are dual boot scenarios with Crouton and maybe a couple that totally wipe it. There has to be a way and I'm sure some of you have done it on here. I would have to use Rufus and create a bootable flash drive which is easy to do. Just asking if you fine folks out there have had any luck doing this and if so how was it? From what I have read online the Chromebook runs better and faster on an OS besides Chrome. Thanks....
