Basically - you would like to have it dropped - but not log any events/alerts in the logs , correct ?

Yes, I would like to have drops, but no alerts logging. In fact, I just need not to log to drop.log, other logs don't have any sense for me.

Using af-packet ips or nfqueue ? What is your set up like?

Using af-packet mode. Interfaces config looks like:

1. AUTOGENERATED by Stamus SELKS set up script
2. Linux high speed capture support
   af-packet: # Put default values here. These will be used for an interface that is not # in the list above.
   - interface: default
   #threads: auto
   #use-mmap: no
   #rollover: yes
   #tpacket-v3: yes
   - interface: eno2
   threads: 8
   cluster-id: 99
   cluster-type: cluster_flow
   defrag: no
   use-mmap: yes
   #mmap-locked: yes
   tpacket-v3: no
   ring-size: 8192
   #block-size: 32768
   #block-timeout: 10
   #use-emergency-flush: yes
   #checksum-checks: kernel
   #bpf-filter: port 80 or udp
   copy-mode: ips
   copy-iface: enp179s0f0
   - interface: enp179s0f0
