Pressing tab doesnt insert tabs, shows autocomplete instead.

Description
Is it possible to prevent the [tab] key from doing autocomplete/suggestions in notebook, and instead add a tab, as expected?
I tried adding "disabled" : true to various entries in the shortcuts.jupyterlab-settings file, but it doesn’t seem to have any effect until using a beta as suggested in the discourse link below.
Code completion is not enabled, (default) in the jupyterlab settings window, so I’m not even sure what is firing the dropdown tooltips.
This is not a question of line indentation, which works. I want the ability to tab the = signs on successive lines so that they line up - with tabs, not spaces.
First two lines are tabbed as desired by copy-pasting tab characters, so tabs are possible, but pressing tab on the next line shows this annoying dropdown instead.
With the beta and json disabling tabs using json below, the behaviour changes to: pressing tab activates the notebook's tab in the tab status bar
{
"command": "completer:invoke-console",
"selector": ".jp-CodeConsole-promptCell .jp-mod-completer-enabled",
"keys": [
"Tab"
],
"disabled": true
},
{
"command": "completer:invoke-notebook",
"selector": ".jp-Notebook.jp-mod-editMode .jp-mod-completer-enabled",
"keys": [
"Tab"
],
"disabled": true
},
{
"command": "completer:invoke-file",
"selector": ".jp-FileEditor .jp-mod-completer-enabled",
"keys": [
"Tab"
],
"disabled": true
}Reproduce
Open a notebook, in a code block type a word, space, then tab.
Expected behavior
\t tab character is inserted
