One tiny last bit: In many releases over the years something *could* go bump in the night and fubar orainventory and/or put a new partial one in a new place upstream of the old one in location searching, so before all y’all add a new home, make sure you back up the old one and know what the latest twists of path searching order do as the net from Oracle, Operating System, and shell layers and whether the environment needs to be dotted or just the script invoked. Sigh. They probably have that all fixed by now, but my paranoia is well earned.

That's a good point - if you've used partitioning there will be entries (deleted) in tabpart$, indpart$ et. al. So maybe after a re-install you'd need to create an empty database and move the data from the old to the new (transportable tablespaces seems the best option for that).
Another thought that's just occurred to me that if you're licensed for the diagnostic and performance tools, and even if you do nothing but keep a history of optimizer statistics there are some sys tables that will be partitioned (by setting an event when the tables are created, I think) so if you remove partitioning from the excutable what happens to them. (Perhaps the "part_off" library has a run-time check that may allow only SYS to create and use partitioned tables).

chopt is a way to go as it is documented here: https://docs.oracle.com/en/database/oracle/oracle-database/19/ladbi/chopt-tool.html#GUID-057E4EFC-74ED-43B3-B03B-C83C5A5D3C7F
The exact commands it uses are in $ORACLE_HOME/bin/chopt.ini.
Here is an example for partitioning (it is basically as Jonathan said with an additional command to make oracle):

It's a very long time since I did one, but the most secure way to deal with the problem is to create an Oracle executable that does not include the bits you don't want to pay for; but many years ago - for UNIX systems - I would use "make" to create new libraries and executables.
If you go to $ORACLE_HOME/rdbms/lib you will find a file called ins_rdbms.mk, this is the control file for make-ing Oracle. If you know where the log files are for the Oracle installation you will find there a file called something like "make.log". At the top of the file you'll find a line like:
/usr/bin/make -f ins_rdbms.mk clean rat_on part_on dm_on olap_on sdo_on rac_off dnfs_off ORACLE_HOME=/u01/app/oracle/product/19.0.0/dbhome_1/
In this line "part_on" is one of the targets for make, and if you search ins_rdbms.mk you'll find the rule that applies for part_on; just below that there's a rule for part_off.
So you could execute make, changing the command line you find to use part_off instead of part_on (and changing the ORACLE_HOME/as appropriate. However, there are 3 things I would do first:
