Hi
To Do this Globally :-
//
The only way to do this without modifying some javascript code (always a bad idea!) is to overlay the parsys component and on the cq:editConfig set cq:disableTargeting to true.
You'll need to modify the following nodes:
foundation/components/parsys/colctrl/cq:editConfig
foundation/components/parsys/cq:childEditConfig
foundation/components/parsys/cq:editConfig
foundation/components/parsys/new/cq:editConfig

You can disable at component level by setting cq:editConfig/cq:disableTargeting to true.

To disable "target" option when edit the component you need to add property cq:disableTargeting="true" to cq:editConfig Node
// cq:actions="[text:Button,-,edit,delete]"
cq:dialogMode="floating"
cq:disableTargeting="true"
jcr:primaryType="cq:EditConfig"

I hope this will help you.
Thanks and Regards
