How to replace marker data in an AIFF file?

I have an AIFF file with incorrect marker data.

How do I replace the markers section of the metadata with the correct text using terminal commands on macOS?

$ afinfo sample.aif

File:           sample.aif
File type ID:   AIFF
Num Tracks:     1

  marker 1, "": frame     75576   SMPTE time 0:00:00:00/0       type 0 (....) channel 0

I need to replace the marker section at the bottom of that output with this:

4 markers; SMPTE time type 0 (none)
  marker 1, "Start": frame         0   SMPTE time 0:00:00:00/0  type 0 (....) channel 0
  marker 2, "End": frame    157819   SMPTE time 0:00:00:00/0    type 0 (....) channel 0
  marker 3, "LoopStart": frame     75576   SMPTE time 0:00:00:00/0      type 0 (....) channel 0
  marker 4, "LoopEnd": frame    103868   SMPTE time 0:00:00:00/0        type 0 (....) channel 0

ChatGPT gave me an answer for using afconvert with the -M option to add markers from a text file but it turns out afconvert doesn’t actually have an -M option.
