Bios update for 15 5558
Hello, I'm currently using Dell Inspiron 15 5558 Laptop with intel i3 4005u processor since its an intel processor it can support "PTT" ie intel's ftpm which can give me tpm2.0 to install Windows 11 so Dell can you enable/add PTT in Bios update for my laptop, please.
Anything older than 6th generation does not have TPM 2.0-equivalent PTT.
While the current pre-release Windows 11 will install, unless Microsoft changes its plans, anyone using it will have to revert to Windows 10, since Microsoft has not changed its official stance: Windows 11 will require TPM 2.0 and an 8th generation or later CPU.
While you can try it now if you wish, don't plan on using it long term unless (a) Microsoft changes its requirements or (b) a new system is in your plans.

Actually I know someone who has 5th gen Intel who has PTT and also got Win11 update!
Unfortunately Dell doesn't list your computer ( Inspiron 5558) for the windows 11 upgrade - see link below)

PTT support began with the 6th generation CPUs -- your 4th generation does not have PTT support, a fact no BIOS update can change.
