I took a peak into the code to see that for myself, and here's what I found.
(Sidenote: Guilliman you got some tidy code. Thanks for making it so others can read it and understand what's happening most of the time.)

This is the command to give you all the relics, give you all the empire modifiers, and complete all the unique research options: gpm_iddqd.1
BTW, it also checks to see if you already have a relic so it doesn't give duplicates.

Here's each individual relic:

gpm_r_ai_architect

gpm_r_banner_of_the_fallen

gpm_r_cloacking_device

gpm_r_codex_administratum

gpm_r_datacube

gpm_r_earthquake_engine

gpm_r_encrypted_sct

gpm_r_encyclopedia_galactica

gpm_r_enigmatic_advisor

gpm_r_experimental_weapon

gpm_r_emegency_replicator

gpm_r_gravity_engine

gpm_r_manufactorium_ship

gpm_r_mysterious_shield_generator

gpm_r_positronic_microchip

gpm_r_power_core

gpm_r_q_storage_compressor

gpm_r_quantum_sphere

gpm_r_self_assembly_hub

gpm_r_sentinel_queen

gpm_r_soul_gem

gpm_r_venerable_dreadnaught

gpm_r_zero_energy_generator

gpm_r_time_displacer

gpm_r_alien_eggs

gpm_r_machine_world_core

gpm_r_mars_rover

And how to get that relics through console command?
I have tried just type one cheat id and the console command replies "unknown command".
Thanks before.

select science or construction ship, open the console (keep ship selected) and type

effect owner = { add_relic = gpm_r_relic_name }

I did already following the order
but on the console replies { invalid relics: "-" }

I have found that "add_relic gpm_r_EXAMPLE" works just fine
