I know that there is a way to disable this with env variable. But for my scenario I don't need Ryuk to be spawn every time I run test containers (I have separate gradle tasks to setup and destroy containers which summons Ryuk when it is needed). Currently I have to use really janky hacks to inject env variable form code. Other option is to set env variable on every machine for our gradle build to work normally which is not ideal either.

For everyone who is wondering what is the scenario. You really don't want to spawn Oracle 20Gb container with Apex and Ords and wait minutes for db to load every time you want to recheck typo in your integration test. Instead we spin containers once at the start and than they run until clean task is called.
