You can improve frequency of the chip, but the card maybe become unstable.

You can refer to chapter 8 of the《ISO-IEC 7816-3》 about TA1, and refer to chapter 5 of the 《ISO 14443-4》about TA1.
And you need to ask card's manufacture to update TA1.

@wumindejia, thanks for your reply. I will check the ISO-IEC 7816 and ISO 14443-4 firstly.
