Calander Reminders uses 1/2 a Gb of RAM

Hi
Noticed Calendar Reminders is taking up 500mb of ram, which is a fair chunk of my 8Gbs, from boot. since i don’t use it at all, any ideas how i can stop it booting in the first place without making parts unstable?
Cheers

Remove kde-pim

sudo pacman -R kde-pim

done so, takes up 200-300 less ram now, cheers!
