Hi Can I check for small SDA sites design, can we directly connect DHCP/DNS server to the Border Node?

As long as the DHCP s not part of a fabric subnet you can, design wise it doesn't sound like the best idea but it is technically possible.
Just do not use a fabric subnet to connect to it (l2 handoff/ipdb/whatever is extended to the border), as it has DHCP snooping configured (which cannot be simply fixed by disabling snooping or trusting a port, as it has some platform dependent restrictions when it comes to vxlan-encapsulated DHCP packets with a destination other than an anycast gateway).
