TYPO3 Core

Currently it is possible to change the configuration of a field through TSConfig only for these values ​​contained in the allowOverrideMatrix of FormEngine.

    protected static $allowOverrideMatrix = [
        'input' => ['size', 'max', 'readOnly'],
        'text' => ['cols', 'rows', 'wrap', 'max', 'readOnly'],
        'check' => ['cols', 'readOnly'],
        'select' => ['size', 'autoSizeMax', 'maxitems', 'minitems', 'readOnly', 'treeConfig'],
        'group' => ['size', 'autoSizeMax', 'max_size', 'maxitems', 'minitems', 'readOnly'],
        'inline' => ['appearance', 'behaviour', 'foreign_label', 'foreign_selector', 'foreign_unique', 'maxitems', 'minitems', 'size', 'autoSizeMax', 'symmetric_label', 'readOnly'],
        'imageManipulation' => ['ratios', 'cropVariants']
    ];

I think it would be useful if it were also possible to change the "eval" value through TSConfig
