How to Set Default Language for website

Hello,
I'm having a NopCommerce website with 2 Languages (English - Arabic) and i would like you make the Arabic as the only language to be displayed to the user and i keep the English Language for myself to use in the Admin panel, however when i set display order to 0 for Arabic and 1 for English, it still shows the English instead of Arabic for new sessions,
the only way that it worked for me is by disabling English but still can't use it in Admin Panel
Note: i'm using the URL as it is without the language codes as i have unchecked "SEO friendly URLs with multiple languages enabled" because i don't want it in my url

Thanks.

Hello,

You can not separate language as per customer role.

This requirement is out of box. however, you can set default language by that display order.

You can do with customization.

like limited to customer role.

Use "Display order" field. This display number is used to sort languages in the public store (ascending). The language with display order 1 will be displayed at the top of the list.
