Hi Lukas,
You could try testpmd Command File Functions
<https://doc.dpdk.org/guides-25.07/testpmd_app_ug/testpmd_funcs.html#command-file-functions>
Rte_flows using this method can be created at boot and run time.

   - If testpmd started with the --cmdline-file=FILENAME command line
   argument testpmd will execute all CLI commands contained within the file
   immediately before starting packet forwarding or entering interactive mode.
   - At run-time additional commands can be loaded in bulk by invoking the
   load FILENAME command.


 Best Regards,
Khadem
