Aluminum wire has been allowed for indoor use since 1946. Per code, the 2017 NEC book covers it's use in section 110.5 titled 'Aluminum wiring'. You have to use alloy or nolox during splicing/connections with copper.

You mean this

110.5 Conductors. Conductors normally used to carry current
shall be of copper or aluminum unless otherwise provided in
this Code. Where the conductor material is not specified, the
sizes given in this Code shall apply to copper conductors. Where
other materials are used, the size shall be changed accordingly.
Informational Note: For copper-clad aluminum conductors, see
310.15.

The use of anti-oxidant paste is pretty much up to the installer. Some
manufacturers recommend using it on their lugs but none require it as
part of the listing and the NEC is silent on the issue.
The strange thing is most lugs are aluminum and actually perform
better with aluminum wire than copper, goo or not.
