TextureFormat ETC2 missing?

When I override texture settings for Android with the format “RGBA Compressed ETC2 8 bit” or setting the texture compression in the Android`s player settings to ETC2 (GLES 3.0) which texture format does the texture get?
When looking at the Texture Format definitions: Unity - Scripting API: TextureFormat

There is no ETC2 defined.

Does it mean that ETC2 is not supported?
Or does it mean it gets converted when loaded?
Or is it just missing in the enum and I will get a value not listed in the TextureFormat enum?

It seems to be available in latest docs: Unity - Scripting API: TextureFormat.ETC2_RGBA8
