DHCPDECLINE messages from an Banana Pi M64 running Armbian 24.11.1 jammy

I have a Banana Pi M64 running Armbian 24.11.1 jammy, which has both a hard wired Ethernet connection and also WiFi. I have several other computers with both Ethernet and WiFi connections.  I have my local DHCP servers set up to offer the same local IP address to both the Ethernet and Wireless NICs.  For most (all but the Banana Pi M64 running Armbian 24.11.1 jammy) this is fine: both NICs get the same IP address and things work fine (generally traffic goes on one NIC).  I do this in case I need to unplug the Ethernet cable (which would cause things to "fail over" to wireless).  The Banana Pi M64 used to also be fine with the same IP address on both its Ethernet and its Wireless NIC, but now it seems to not like that, I believe because its dhcp client is bothering to check.  How do I turn that checking off?
