Override cropVariants for page media field only

Question

I have set some cropvariants in my page.typoscript file using TCEFORM.sys_file_reference.crop.config.cropVariants

Works just fine. Now I would like to override these variants for the page "media" field because no cropVariants are needed here. I found the option to override the TCA for certain CTypes (tried this and it works):

$GLOBALS['TCA']['tt_content']['types']['textmedia']['columnsOverrides']['assets']['config']['overrideChildTca']['columns']['crop']['config']

I am trying to make this work for the pages TCA. I tried

$GLOBALS['TCA']['pages']['columnsOverrides']['media']['config']['overrideChildTca']['columns']['crop']['config']

as well as (shot in the dark)

$GLOBALS['TCA']['pages']['media']['config']['columns']['crop']['config']

Any ideas? Bonus points for a typoscript only solution that doesnt require a TCA override in a php file. Thank you!

Try this:

$GLOBALS['TCA']['pages']['columns']['media']['config']['overrideChildTca']['columns']['crop']['config']
