DHCP gives an IP when the DHCP relay is not in the subnet

[Mik J]

Hello,
Is it possible that the dhcp offers an IP but the dhcp relay is not in the subnet ?
I have a vlan 192.168.1.0/24 and 3 dhcp relay. Each dhcp relay will use a loopback to relay the dhcp request 10.1.1.1 or 10.1.1.2 or 10.1.1.3. The client machines will receive an IP in 192.168.1.0/24
Is it possible ?
NB: if there's a DHCP relay in 10.1.1.4, I don't want to offer an IP in 192.168.1.0/24
Do you have a link or keywords that would help to find the typical configuration for that
Thank you
