Can you explain to me what this BDTS firewall function is for?

Hello.
Use passive detection mode – concerns Dynamic Host Configuration Protocol (DHCP) device detection. When this setting is off, the Bitdefender firewall listens for DHCP packets only on port 67 UDP. When it’s on, the firewall listens and receives all packets without interfering with DHCP servers that run on the local machine.
Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway. RFCs 2131 and 2132 define DHCP as an Internet Engineering Task Force (IETF) standard based on Bootstrap Protocol (BOOTP), a protocol with which DHCP shares many implementation details. DHCP allows hosts to obtain required TCP/IP configuration information from a DHCP server.

Thanks for the explanation, do you think I should activate it or better leave it deactivated (which as I understand should be the default option) for the purposes of device and network security?
From the comment it seems that it is also used to scan the vulnerabilities of devices that connect to WiFi so I'm not sure what to do..
