Exclude services from triggers prototype in LLD rules

[Centurion]

Sorry I forgot to specify versions and I cannot modify my first topic.

Hi,
Can someone help please.
I am new to zabbix, I read the documentation and I am trying to exclude some windows services from trigger prototype, but I can not do it.
Could someone explain me how to proceed please.
Thank you in advance

OS version : RHEL 7.7
Zabbix version : 4.2.4
