Yes.

For graphlink locking, change the type byte, the first byte in it's entry in
the VAT.  For non-graphlink locking, add or remove a byte with value
$FF from a non-executed portion of a program (that's after all labels).

> Or changing the name or hiding it?

Change it's name in the entry on the VAT.  Hiding it just involves
making the first letter of the name illegal.

Note: the VAT starts at the end of RAM page 7 and works backwards.
