I have this javascript that keeps on getting called on so my idea here is to get the value from the Order_setting model and check if a certain column is disabled like Order_setting::variable. So when Order_setting::variable is disabled wanted to hide the certain option from the repeater which is location on backend from Products see image.

Is this possible that I can get a value of a model from js and hide certain element from the repeater?

You could set the value in JS via a view file, then it would be available via JS

<script>
var MY_VARIABLE = '<?= OrderSetting::first()->variable ?? null ?>';
</script>
