Hello Kai,

THank's for your question.

We do not offer any IO expanders with 64 addresses.

The best solution we can offer for this is to use either a higher GPIO count-IO expander to lower the total number of ICs needed.

Then if using a higher IO count isn't enough, then the use of I2C Controlled switches (such as TCA9548A) to select the devices on the bus of interest. This would give you a theoretical maximum devices of 8 * 8 = 64.
