Player Contract Expiration Date

[Jammer]

Question pertaining to Kyrie Irving, who has a Player Option for NEXT Season.

If Kyrie Irving formally declines his player option for next season, is there a way for his contract to expire before June 30 so that he loses the Designated Player Designation and the Celtic's can trade for another Designated Player, like Anthony Davis, before July 1?

For example, can the Celtics and Kyrie mutually void his contract on June 25, or can they have it expire prior to June 30??
