It is possible.

Show all of your changes, folders. Make screenshots.

Okay, so you have removed all of the technologies and added only three?

There's more than just buildings and units—you have to also modify governments, laws.

game/Governments.json

REQUIRED_TECHNOLOGY: -1,

## To disable required technology: -1

game/laws/Laws.json
RequiredTechID: [-1, 44, 54, 61, 89],
->
RequiredTechID: [-1, -1 , -1 , -1 , -1 ],

## To disable required technology: -1

game/units/

All the files:
RequiredTechID: -1,

game/buildings/Buildings.json
game/buildings/BuildingsResources.json

RequiredTechID: [-1],

RequiredTechID: [-1, -1],

All scenarios, or the default scenario, need to change the default technology ID if is larger than 2(lower than all of your technologies counted from 0).
Scenario Editor -> and in the last menu -> "Unlocked technologies"
