Yes, this was implemented in [2.02.11](https://fmod.com/docs/2.02/api/welcome-revision-history.html#20211)

> - Core API - GameCore - Added in [FMOD\_GameCore\_XMAConfigure](https://fmod.com/docs/2.02/api/welcome-revision-history.html#fmod_gamecore_xmaconfigure). This can be used to control whether to allocate XMA codec hardware resources inside [FMOD::System\_Create](https://fmod.com/docs/2.02/api/welcome-revision-history.html#fmod_system_create). If not called before [FMOD::System\_Create](https://fmod.com/docs/2.02/api/welcome-revision-history.html#fmod_system_create) the resources will be allocated on first codec use.

You will need to call this function before the `FMOD.System` is created, which is easiest to achieve by adding a `PreSystemCreate` implementation to the FMOD Unity GameCore platform:

```diff
//Assets/Plugins/FMOD/platforms/gamecore/src/PlatformGameCoreScarlett.cs
namespace FMODUnity
{
     public class PlatformGameCoreScarlett : Platform
     {
...
+ internal override void PreSystemCreate(Action<FMOD.RESULT, string> reportResult)
+ {
+ reportResult(FMOD.GameCore.XMAConfigure(false), "FMOD.GameCore.XMAConfigure");
+ }
...
    }
}

```
