Anonymous http -post request to SAS Viya4

[thesasuser]

Hello

We are using SAS 9.4 environment to process http post request from within the organization.
These requests are anonymous (i.e.,no user authentication needed). The response (json/xml) is generally delivered in  500-700 milli-Seconds.
The requests originate from non SAS processes.
We are exploring the possibility of moving this process to Viya4 and have set a test process  using postman. This is a two step process. Authentication itself takes 2+ seconds.
Wondering if there is a way to by pass the authentication.
