To get rid of that unnecessary endeavouros reload, you may want to modify the github mirror order at file /etc/pacman.d/endeavouros-mirrorlist to:
## Github Server = https://github.com/endeavouros-team/mirrors/releases/download/mirror1/ Server = https://github.com/endeavouros-team/repo/raw/master/$repo/$arch
Both of those mirror addresses will be supported at least for a few months from now, so the change should be a safe thing to do.
And if EndeavourOS mirrors for some reason happen to change, we’ll update the
endeavouros-mirrorlist package for you in order to keep things working as expected.
