Generally, yes, mnemonic phrase contains enough data for software wallets to derive the keys. With the caveat.
Some software wallets imports are supporting only 12 word or 24 word combinations. Some support different BIPs and thus path derivation schemes (32/44/84) by default, and some only single one of them. Some have additional feature for a specific seed ...

It would be trivially brute forceable.
There are 2048 BIP 39 words. If you change two words AND the position is known, it's simply a matter of computing all possible combinations of what those two words can be replaced with - 2048*2048. That's only 4194304 - A smartwatch could do that in a few minutes without breaking a sweat. It would take you longer to ...

If you want your wallet database (file) to be in a different directory than your data directory, you can use the -wallet=<path> startup option to specify a custom path to your wallet.
Quoting the manpage:
-wallet=< path >
Specify wallet database path. Can be specified multiple times to
load multiple wallets. Path is interpreted relative to <...

Even in the absence of active attackers, there are many reasons the Bitcoin network could diverge, such as:
Large scale internet routing issues - we've already seen these with BGP routes being incorrectly broadcast, leaving large chunks of the internet temporarily inaccessible from other large chunks. In ...

It's more safe to do it on "clean" operating system.
I can propose another solution:
Prepare DVD or USB stick with Ubuntu operating system
Start live session of Ubuntu from DVD or USB stick on your computer
Download Electrum AppImage from official Electrum website
Run Electrum, generate seed
Switch off computer, all data will be lost

Identity leaks usually happen in two places.
Off Chain Leaks
Here, the address is somehow linked to you off chain - this could be because you shared it from an account or network that can be traced to you (it's largely impossible to avoid being tagged online if a well funded and skilled group, such as nation states, is targeting you).
Alternatively, if you ...
