enable_systemd_timers=('fstrim' 'pkgfile-update') is in profile.conf but calamares did not enable them.
Should it work?
I assume you used the packaged version of the tools and not those from git. Since we use github actions to build our ISOs we rarely update the tools in our binary repos. You can try to build your local copy of the tools via this PKGBUILD and try again: Packages / Extra / manjaro-tools-git · GitLab
Also use a service like pastebin and provide the full build log and check the generated config files on your ISO in /etc/calamares/modules
