@Nativ Issac​ I would suggest to use a PAT token created on behalf of a service principal and grant SELECT privilege only to the service principal to the targeted catalogs/schemas/tables. Thus you can restrict the access to the data using JDBC. Please refer to below docs on the same topic. Hope this helps.
