@ProdStar:
Set decrease_type = 0 for making it a permanent item and set available_period = 0 for stopping the timer.
Code:
USE [Arcadia]
UPDATE ItemResource
SET decrease_type = 0
WHERE id = 540073
UPDATE ItemResource
SET available_period = 0
WHERE id = 540073
GO
This self-written query should do this, I did not test it ingame, but it should work.
