I get the following error on running make:
make[1]: *** /lib/modules/6.6.26-v8+/build: No such file or directory. Stop.
make: *** [Makefile:17: build] Error 2

You can try the solution of another user and link the kernel-header directory from /usr/src to the kernel version directory in lib/modules.
In his case it was sudo ln -s /usr/src/linux-headers-6.1.21-v8+ /lib/modules/$(uname -r)/build

Or you can try adding "arm_64bit=0" to config.txt, reboot and make again

Thank you. But I want to run a 64-bit build. The first option does not work. Are you saying the Phoscon RTC module does not support 64-Bit?

No. It just means that you don't have the kernel headers for this kernel version yet. I think the raspberrypi-kernel-headers package is always a little bis slow with that. see this forum post related to kernel headers: https://forums.raspberrypi.com/viewtopic.php?f=28&t=276122
