The mechanism is called ARP.

You have no method to prevent one interface from responding to ARP
requests under any circumstances. If you had logic to disable one
interface when the other was working, then you could use ARP as
failover mechanism.

You have mentioned one mechanism so far.  You claim "There are many ways to
do network interface failover in Linux".  Maybe you can list or name at least
two more of them just so I can see what you have in mind.  If one of them is
suitable for my situation, I'll even consider using it.

VRRP and OSPF. My personal preference is to use OSPF, assigning the
service IP address to a loopback interface and advertising its
availability across both physical interfaces.
