Unfortunately, once modules are installed they become persisted and part of the Array's permanent system config. Then they can only be removed by doing a destructive re-initialize. (factory reset). This has been the same for a long time.  There are some cases where modules can be upgraded/swapped though, and you can use the mydocs website to create the instructions and of course you can engage support to check/clarify your options.
