DHCP in another vlan and switch without DHCP relay - is it possible to forward?

There is a D-Link DGS-1500-28 switch. There are several vlans and a common DHCP for them with a bunch of configured pools. DGS-1500 does not support DHCP relay. Is it possible to carry out DHCP forwarding in this case? If yes, please explain how.
The option to throw out D-Link and take a budget tsiska is not considered.

it seems to me that the minimum L3 switch will cost a little more than the minimum L2 with dhcp-relay, and you won’t have to fence crutches.
if you really want, then the ports are definitely in the trunk, so that the vlans reach L3 unchanged .. and from there everything is already relayed.

As an option, configure D-Link all in one VLAN and enable port-isolation

why is it impossible to transfer the port that goes to the trunk on dhcp, or simply, along with one untagged vlan, start up the required number of tagged and parse them already on the server side?

It is necessary to allow circulation of broadcast packets. But this is how you plant the entire network.
Better change the switch, or
Or make a single gateway for all networks on the same host, and set DHCP on it
