Are both DHCP servers on the same broadcast domain? If yes, then that would explain it.

If I understand well your question, NO.
The router DHCP, always served for machines attached to mydomain.net and it is their default Gateway
The 3 lab machines (1 serves as DNS and DHCP for a domain called my2ndDomain.demo, server and win 10 are attached to this domain) in the other subnet 192.168.95.0
AS I said, I added 1 static route to the router for subnet 192.168.95.0, its Gateway is the IP of the Hyper-V machine 192.168.1.28 that is hosting the Lab and it is working fine except this strange behavior where the laptop in the 192.168.0 is getting IP details from the DHCP in 192.168.95.0 DHCP. When I stop the DHCP server in the subnet 192.168.95.0 and do IPCONFIG /renew on the laptop, it gets back its IP details from the router correctly

Is the Hyper-V machine set up to route or bridge between the two subnets? If it's bridging, then DHCP requests on the 192.168.1.0 subnet are going to leak over to the 192.168.95.0 subnet and the lab DHCP server is going to answer. The other possibility is that the Hyper-V is set up as a DHCP relay.

Do you mean that the DHCP role is etup on the HYper-V?
No, the HYper-V has no DHCP role setup?
Do you mean a property configured in the HYper-V settings? if yes, what is this property and in which place I can find it?
I have only 2 virtual swithces setup on 2 NIc cards
