I run gh repo clone FFTW/fftw3 then sh bootstrap.sh and sudo make and sudo make install. It succesfully installed, then i run dpkg -l 'libfftw3*' that tells me that 3.3.8 exists on my system (linux bullseye 11 kde)

3.3.8 was installed by your linux distribution (by the way, are you sure it's bullseye? bullseye is a debian distribution, but the package names mention ubuntu)

Basically, you have fftw-3.3.8 in /usr/include and /usr/lib (installed by the system) and fftw-3.3.10 in /usr/local/include and /usr/local/lib (installed by you). This may or may not be what you want.

I would venture a guess that you would be ok with the default installation that comes with your linux distribution. If that's the case, you want to remove the files that you installed in /usr/local (they are harmless but you don't want to get confused in the future). Try "make uninstall", which used to work decades ago. If that doesn't work, remove everything that looks like fftw in /usr/local/include and /usr/local/lib (and perhaps /usr/local/man and /usr/local/info, I forgot what gets installed by default).

I want to update to 3.3.10 cause i would like to install imagemagick 7, but imei 7 needs a newer ffw. So what i must do in order my system use the newer ffw instead of the old installation? 

Distributor ID: Debian
Description:    Debian GNU/Linux 11 (bullseye)
Release:    11
Codename:   bullseye

Is upgrading your debian installation an option?

The next debian ("bookworm") is currently in a soft-freeze state and will be released officially in a few months. It provides 3.3.10 out of the box. I upgraded from bullseye myself a few weeks ago with no issues. If this route is viable to you, it is by far preferable to attempting to keep multiple versions in one system.
