How to reject ACK/NACK from other Send Ports to Orchestration

Question

Hi Everyone,
I have a below scenario, Please let me your ideas how can we avoid ACK from other send ports (If there is any failures), in my current scenario getting issues or conflicts because of this
AckRequired.
Key points in my scenarios
SendPort_A is pointing to SAP
SendPort_B is pointing to SQL
Flow
Receive MessageA and Transform to MessageB format, send MessageB to SendPort_A which directly bind to orchestration with transmitted property enabled.
SendPort_B subscribes the same message, output of map with message type as filter condition (we are not expecting any Acknowledge from sendPort_B, because it’s a generic send port for some scenario).
Problem
When I see the context properties both send ports has AckRequired
Property to true (so getting ACK/NACK from both send ports).
I want acknowledgement only form SendPort_A which is bind to orchestration with transmitted property enabled, but not from the SendPort_B which subscribes just with message type.
I have tried the below points but no luck
Created custom pipeline with custom pipeline component to set / overwrite
AckRequired Property to false (Pipeline component is working fine, but nothing is overwriting in context, getting acknowledge back to orchestration for any failure in SendPort_B)
#region IComponentUI
public IBaseMessage Execute(IPipelineContext pContext, IBaseMessage pInMsg)
pInMsg.Context.Write("AckRequired", "http://schemas.microsoft.com/BizTalk/2003/system-properties", false);
return pInMsg;
#endregion
Below images gives some info on the same scenario.
Appreciate your suggestions.
Thanks, SMS Vikas K

Hi Vikas,
Let me know if I understood correctly.
SendPort_B subscribes the same message, output of map with message type as filter condition (we are not expecting any Acknowledge from sendPort_B, because it’s a generic send port for some scenario).
Problem
You have a send port B which is subscribing to the same message using the message type.
You can set additional filters to ignore Acknowledgement-
Ex- Mgtype= "" AND
AckRequired!=True OR
AckRequired!=False
