Read-back feature on a DE10-Nano?

I am working on a design with the DE10-Nano (5SCEBA6U23I7), loading the program via JTAG, a .jic file. My question is, since this is a design of my own and I don´t want it stolen or pirated: Is there a way someone with this FPGA to extract the program, with some kind of read-back feature/software? Reading about it I found that it highly depends on the manufacter and model, but I didn´t find anything specific on this one.

I tried with the "Examine" feature on the Quartus programmer, but I´m unable to check the box. The only way I can do it is by loading in the EPCS the .jic file that is already loaded on the FPGA, and I can save the file thus creating a copy of the one I already have, so this means that someone without the file itself will be unable to copying it? Is there an option I have to select to make sure the file loaded in the device will be secure/"encrypted" against piracy? Thanks.
