Yes, that's an option:

https://lists.isc.org/pipermail/dhcp-users/2013-September/017193.html

  class "msft-wpad" {
    match if substring(option vendor-class-identifier, 0, 4) = "MSFT";
    option dhcp-parameter-request-list = concat(option dhcp-parameter-request-list, fc);
  }

This sends option 252 (0xfc) to Windows client, preventing them from
spamming with INFORMS later.
