They are already enabled, just run:

config-pin P9_24 uart
config-pin P9_26 uart

config-pin P9_13 uart

How can I enable UART1 and UART4?

I added "cape_enable=bone_capemgr.enable_partno=BB-UART1,BB-UART4" to the uEnv.txt.

But seems are not working.

How can I doublecheck if the UART are enabled?
