How to keep edited rules alert->drop

I am running suricata inline mode and I am changing alert → drop all the rules related to malicious traffics and I am making those changes in suricata.rule file. Everytime I run the suricata-update rules changes to alert mode. Appreciate the assistance how to make those changes permeant. I tried .modify but its not working

You will want to create a drop.conf file. In this file you can list the SIDs, one per line that you wanted converted to drop. Suricata-Update will then convert them.

Typically this file is kept at /etc/suricata/drop.conf, but it will really depend on how you installed Suricata. If its not being picked up, you can provided it on the command line:

suricata-update --drop-conf /etc/suricata/drop.conf

It works. Thank you very much for the swift response. I would like to know is there a way to drop rule base on words. following are I am trying to drop.
