No.

If you, by any reason wants bind-9 to use port 53

The ARM manual says :
6.2.14.5. Query Address

If the server doesn't know the answer to a question, it will query other nameservers. query-source specifies the
address and port used for such queries. For queries sent over IPv6, there is a separate query-source-v6 option. If
address is * or is omitted, a wildcard IP address (INADDR_ANY) will be used. If port is * or is omitted, a random
unprivileged port will be used. The defaults are

query-source address * port *;
query-source-v6 address * port *;

    Note: The address specified in the query-source option is used for both UDP and TCP queries, but the
    port applies only to UDP queries. TCP queries always use a random unprivileged port.
