Unable to get BIOS attribute correct to PATCH

Hello,
Tring to do a PATCH for a BIOS attribute but cannot get the curl payload correct.  I have not seen this implementation of the attributes before.  Is this even a supported method?  See below.

I tried the below but returns a malformed.
curl -u supportuser:support@eviden -k -H "X-Auth-Token: $token" -X PATCH 141.112.43.234/redfish/v1/Systems/system/Bios/Settings -d '{ "Attributes": {"PchSetup-\gt;PchSata_0": "0x01" } }'



curl -u supportuser:support@eviden -k -H "X-Auth-Token: $token" -X PATCH 141.112.44.222/redfish/v1/Systems/system/Bios/Settings -d '{ "Attributes": { "PchSetup->PchSata_0": "0x01" }}'
