Dashboard permissions

lucy_wilshaw ,
To avoid users from exporting a visual's data, you can simply go to the visual's Format -> General -> Header Icons -> Disable "More Options"  

Also, to avoid users from accessing the underlying data, you can simply provide just the report's read access to the users without adding them to the workspace.

Hi,lucy_wilshaw 

Apart from the above mentioned ways, you can also try the following ways:

1. Create a subscription to the dashboard and restrict the user's rights, in this way you can not only restrict their access to the current dashboard but also realize that the user receives new dashboard information on a regular basis.

Here is the relevant documentation:
Email subscriptions for reports and dashboards in the Power BI service - Power BI | Microsoft Learn

2. If you wish to disable export or download for a user, you can do so in the admin portal if you are an administrator.

3.You can also turn off the following Settings when sharing links:

Same with the report:
