This appears to be a core bug as it is also happening with native FAL fields. Symptoms are:

• The POST payload still contains hidden=0 after toggling the state to hidden. Suspecting some JS issue either when collecting the values or compiling the payload before sending.
• It appears to only affect the first relation in native FAL fields but all relations in FlexForm context.

adding this to Configuration/TCA/Overrides/sys_file_reference.php solves the issue:

$GLOBALS['TCA']['sys_file_reference']['columns']['hidden'] = [
    'exclude' => true,
    'label' => 'LLL:EXT:core/Resources/Private/Language/locallang_general.xlf:LGL.hidden',
    'config' => [
        'type' => 'check',
        'renderType' => 'checkboxToggle',
        'default' => 0,
    ],
];
