How to disable Ping packets from LAN port on mikrotik?

Answer 1

This is hardly the reason. Why is mikrotik sending a ping? Unlikely. But in any case, try
Full blocking from the router towards your wd if its ip 192.168.0.2
/ip firewall filter
add action=drop chain=output dst-address=192.168.0.2
or only ping
/ip firewall filter
add action=drop chain= output dst-address=192.168.0.2 protocol=icmp

Answer 2

In the firewall, deny ICMP traffic to the ip of this storage.
