How to hide 'share with orgnaization' option for customer

[Demo Agent JSD]

Hi Team,

I have a case where, my customer belongs to multiple organizations, so while creating ticket, customer used to get option to share with organizations, where he can select, I actually want that option not to be visible to him and by-default the ticket is shared with all the organization to which the customer belongs, can we somehow hide the same?

Thanks
