Awesome MicroPython has a LED Segment display category, which lists: TM74HC595 - Driver for shift register controlled 5 pin display modules.

Does it work for daisy chain displays?

>>> import TM74HC595
>>> TM74HC595.TM74HC595Controller(sclk=21, rclk=22, dio=23, num_displays=4).test()

points to "Yes".
