I think that you are looking to provide a "LOCATION" for your database on DBFS. When you provide a location for your database all the tables will be created within that folder by default.

See a create table example below:

CREATE TABLE [ IF NOT EXISTS ] table_identifier
  [ ( col_name1 col_type1 [ COMMENT col_comment1 ], ... ) ]
  USING data_source
  [ OPTIONS ( key1 [ = ] val1, key2 [ = ] val2, ... ) ]
  [ PARTITIONED BY ( col_name1, col_name2, ... ) ]
  [ CLUSTERED BY ( col_name3, col_name4, ... )
      [ SORTED BY ( col_name [ ASC | DESC ], ... ) ]
      INTO num_buckets BUCKETS ]
  [ LOCATION path ]
  [ COMMENT table_comment ]
  [ TBLPROPERTIES ( key1 [ = ] val1, key2 [ = ] val2, ... ) ]
  [ AS select_statement ]
