Hi Christophe,
Thanks for your interest with Syncfusion components.
We have checked the reported scenario. Unfortunately, your attachment is not available. We suspect that you are mentioning selection box as the blue box appears while selecting shape elements If so, this can be removed by setting path element focus outline as none.
<style>
path:focus { outline: none; }
</style> |

Sample for your reference, can be found from below link,
If this is not your exact scenario, kindly revert us with more information if possible share some screenshots, which will be helpful in further analysis and provide you the solution sooner.
Regards,
Dharani.
