The ALTOTP IP is only supported for ASIC (Hardcopy devices). The OTP fuse in Arria 10 device has a different purpose from the ALTOTP IP in ASIC (Hardcopy devices). The OTP fuses main function in Arria 10 device is for design security purpose and not to program unique ID/code purpose. You can refer to AN566 application note regarding on the design security purpose for FPGA device that provide the OTP type key option (non-volatile key) or re-programmable type key (volatile key).
You can read the Arria 10 device handbook to understand the what are the features being offered in Arria 10 family devices:
