Disable taxonomies

Hi,
I have to disable the transalation options of two taxonomies.
I try it with a wpm-config.json file

{
“taxonomies”: {
“pa_color” : null,
“pa_talla” : null
}

into my plugin folder, but there is not effect.
This only works if I put this into wp-content/plugins/wp-multilang/configs/plugins/woocommerce.json

I know another way is possible for do that, with actions

What should I do ?

add_filter ( ‘wpm_post_post_config’, ‘__return_null’);

Thanks,
