UEFI doesn't boot SCCM PXE

[Evgeniy77]

SCCM + WDS Server
Microsoft Endpoint Configuration Manager (version 2103)
Site version 5.0.9049.1000
SCCM and DHCP (different servers) in one VLAN, problematic clients in another
Communication configured via iphelper
When loading the client through Legacy, there are no problems
When booting a client via UEFI, the error “PXE-E16: No offer received” appears, at the stage of searching for a PXE server
The same PCs, provided that they are in the same subnet, in the same VLAN with SCCM, boot in different modes correctly. The problem appears only with clients in a separate VLAN
Wireshark shows that the SCCM server is receiving and responding to the broadcast request from the client. The client receives an IP address from DHCP, but then does not make a request to the SCCM server.
Tried:
Updating firmware on HP PCs and laptops
Changed TFTP block size on sccm server
Various IPhelper settings based on recommendations on forums and websites
Help with any conscience.

I suggest using a Microsoft Community forum for IT Pros

Here is a thread that discusses the issue.
