Can the maximum string length for process parameters be increased?

When we invoke our AEM processes via REST endpoints - i.e. processes created in Adobe Workbench, we are getting an error if the string exceeds 2000 characters:

Invalid input. The maximum length of 2000 characters was exceeded.

Is there a way to increase the maximum allowed length?

It is being sent in the body:

It is not recommended to send whole data in the query parameters rather in the body. Please try the same by sending the data in body.

Thanks,

For Json results, it will be the "max json results" at the default get servlet[1]
