label_alt + label_alt_force for IRRE childs cannot be overwritten using OverrideChildTca()
I tried to overwrite childs (IRRE) appearance (label_alt, label_alt_force) for performance reasons in BE (https://forge.typo3.org/issues/82730):
'columns' => [ 'childs' => [ 'config' => [ 'type' => 'inline', 'foreign_table' => 'tx_ext_domain_model_child', 'foreign_field' => 'parent', 'overrideChildTca' => [ 'ctrl' => [ 'label_alt' => '', 'label_alt_force' => false, ] ], ], ], ]

overrideChildTca can currently only be used for overriding types and columns but not the ctrl section, see
\TYPO3\CMS\Backend\Form\FormDataProvider\InlineOverrideChildTca. This is not really easy to solve as code like BackendUtility and others rely on checking the TCA directly without passing required information like the parent table.
don't expect that to be changed, even more I tend to close this issue - it is certainly a feature and not a bug.
