Hi RDobk,
There is no such JTAG IP in the Intel Quartus tools to support JTAG programming for non-Intel FPGA device (Lattice). You need to build your own JTAG logic into the Arria X device to perform the programming to the Lattice device. Otherwise you my consider to contact 3rd party vendor that offer JTAG In-System Programming for both Intel and Lattice FPGA programming. You can refer to the following for the list of available 3rd party vendor that provide JTAG In-System Programming support:
