blacklist inputs.conf

[splunkcol]

I need that the "notice" type logs are not forwarded to the indexer

I know I should add a line called "blacklist" but I'm not good with regular expressions

Another question, why in some threads they talk about modifying the file "props.conf" and "transforms.conf" what is the difference between doing it from inputs.conf and the other way?

inputs.log

[monitor:///folder/folder/folder/ip_firewall]
disabled = false
host = namefirewall
index = firewalls
sourcetype = fgt_log

The blacklist setting controls what sources (files) Splunk reads.  It has no bearing what content within that source is accepted.

Props and transforms are what we use to discard and/or modify events before they are indexed.  See https://docs.splunk.com/Documentation/Splunk/8.1.0/Forwarding/Routeandfilterdatad#Filter_event_data_... for an example.
