Unity's addressables project config API is private. This hack provides a public API for some parts of the ProjectConfigData and can be easily extended.

SettingsAdapter.cs

namespace UnityEditor.AddressableAssets.Settings
{
	/// <summary>
	/// Adapter to provide a public API into <seealso cref="ProjectConfigData"/> internals.
	/// </summary>
	public static class ProjectConfigDataAdapter
	{
		public static bool generateBuildLayout
		{
			get => ProjectConfigData.generateBuildLayout;
			set => ProjectConfigData.generateBuildLayout = value;
		}

		public static bool ignoreUnsupportedFilesInBuild
		{
			get => ProjectConfigData.ignoreUnsupportedFilesInBuild;
			set => ProjectConfigData.ignoreUnsupportedFilesInBuild = value;
		}
	}
}
