you can tweak this file using a bbappend e.g.

recipes-core/base-files/base-files_%.bbappend with content e.g.

do_install_append () {
        if [ "${@bb.utils.contains('DISTRO_FEATURES', 'systemd',
'systemd', '', d)}" = "systemd" ]; then
                echo "export SYSTEMD_PAGER=/bin/cat" >>
${D}${sysconfdir}/profile
        fi
}

will set cat to be default pager for systemd tools.
you can do anything in that do_install snippet.
