Set NoDisplay=true in powerdevil autoatart
Sorry for the confusion.
More context is about show system provided autostart in the UI: plasma-desktop!253 (closed)
This property won't affect the ability of autostart (FYI Hidden=true is disable). NoDisplay only means it would not be displayed in relevant UI. https://specifications.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.html
I believe powerdevil is one of those should not be displayed by default. (Like plasmashell: https://github.com/KDE/plasma-workspace/blob/9f2abd0a54d51d9234a5a9489d1342b261429fa3/shell/org.kde.plasmashell.desktop.cmake#L62)
Do you have any concerns about this?
Nope, sorry, was confused as commit did not contain any context.
