The problem is more than Secure Boot (though I believe the T3600 does not have the capability of Secure Boot having been introduced with Windows 7). You have TPM 1.2 and an unsupported CPU. So if you do manage to install Windows 11 on your system you will not receive updates from MS. It is not clear which updates you would not receive but you would run in an unsupported mode.
And this video describes the waiver you would have to agree to upon installation.
@speedstep Personally I would clean install anyway. Rather than have the update on top of Windows 10 I am one for wiping everything and starting fresh.
The problem with clean install is that Apps that I actually use go away like Skype, MSPAINT, etc. Lots of deprecated features with every clean install of windows. I didn't lose anything because I know how to reinstall 10 clean then upgrade to 11 keeping things like skype intact.

Microsoft recommends against installing Windows 11 on a device that does not meet the Windows 11 minimum system requirements. If you choose to install Windows 11 on a device that does not meet these requirements, and you acknowledge and understand the risks, you can create the following registry key values and bypass the check for TPM 2.0 (at least TPM 1.2 is required) and the CPU family and model.
Note: Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

In reference to unable to boot with UEFI selected. Your disc is likely formatted "MBR" and it needs to be formatted "GPT" for UEFI.

Adding to what fireberd said - If an HDD was loaded in Legacy mode, UEFI mode won't find it and vice-versa.

As Punishment for using windows insider edition you must CLEAN INSTALL 11 wiping everything. Even on supported model.
Keep your files is NOT an option.
This is why I made a throw away system so that If this was the case I didn't lose anything Important.

Microsoft has added a hack to use if you have Windows 10 and TPM 1.2 enabled.
I used this on a T1700 and T3600 and it worked fine.
Microsoft reveals how to install Windows 11 on unsupported PCs with TPM 1.2 MOSETUP method
https://www.microsoft.com/software-download/windows11
Warning:
Microsoft recommends against installing Windows 11 on a device that does not meet the Windows 11 minimum system requirements. If you choose to install Windows 11 on a device that does not meet these requirements, and you acknowledge and understand the risks, you can create the following registry key values and bypass the check for TPM 2.0 (at least TPM 1.2 is required) and the CPU family and model.
Registry Key: HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
Name: AllowUpgradesWithUnsupportedTPMOrCPU
Type: REG_DWORD
Value: 1
Note: Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
