Is it possible to use this model without ECMWF MARS access?

[ThomasMGeo]

When I try to download the assets (specifically surface fields), it requests MARS access.

Wondering if it's possible to download the assets without this access?

The below is output from this: !ai-models --download-assets --assets ~/share/ai-models-assets --assets-sub-directory fourcastnetv2-small
