Never seen that either, POSIX doesn't suggest any support for that either, with this in the RATIONALE section:

The OPTIONS section is listed as "None" because there are no options recognized by historical dd utilities. Certainly, many of the operands could have been designed to use the Utility Syntax Guidelines, which would have resulted in the classic hyphenated option letters. In this version of this volume of POSIX.1-2024, dd retains its curious JCL-like syntax due to the large number of applications that depend on the historical implementation.
