For anybody interested, you can use following snippet:

FMOD::Studio::System* StudioSystem = IFMODStudioModule::Get().GetStudioSystem(EFMODSystemContext::Runtime);
	if (StudioSystem != nullptr)
	{
		FMOD_RESULT Result = StudioSystem->setParameterByNameWithLabel("Footstep_Material", Param);
		if (Result != FMOD_OK)
		{
			UE_LOG(LogTemp, Warning, TEXT("SetFootstepParam(): Failed to set audio parameter, %d"),(int)Result);
		}
	}
