Increasing the limit of job numbers created by Parallel:Matrix

I’m trying a CI job with many variations tanks to the parallel:matrix functionality. The problem is, I have more than 50 variations, so the pipeline fails when reading the YAML file because the job variations count exceeds the limit.

So my question is, how can I increase that limit? I know it’s possible to increase the limit for the needs keyword for instance, but I haven’t found an entry in actual_limits that would appear to be for parallel matrix.

Additional info: the job in question is in a child pipeline with a generated CI file. Currently my workaround is to create an individual job for every variation.
I’m on Gitlab FOSS 14.1.2 and my Gitlab Runner uses the latest version of the Docker image.

Thanks for your help!
