Hi Ebi, 

Greetings from Syncfusion Support. 

We have checked the case at our end, since we could not add or remove the tab items based on the condition provided in the shared code we suggest you to use Disabled property using which we can dynamically enable or disable a tab item based on the conditions. Also, currently we have a breaking issue to use Disabled property that will work on our 17.3.17 ej2.min.js file. We will include the issue fix in our upcoming patch release expected to be rolled out in the mid of November 2019. You can keep track of the issue form the following link.

Meanwhile we suggest you to use our 17.3.17 CDN links and for the same we have shared a sample for your reference that can be downloaded from the following link.
