It is possible to install phpmyadmin on raspberry 64 bit and it even was not difficult in my case.
I am running several hp-laptops with openSuse Tumbleweed and some Raspberries.
On the latest Raspberry 3 B + I 64bit raspbian buster light, kde plasma Desktop.

I am using nginx 1.14.2 with fastcgi (not using 'sock') and php 8.0.10 (php-fpm).
I downloaded 'composer' first. (Use apt or aptitude for that).
After that go to https://docs.phpmyadmin.net/en/latest/setup.html
Look for the shell command
composer create-project phpmyadmin/phpmyadmin
It will install a complete directory 'phpmyadmin' in the current directory.
Move that to /var/lib/ and set the user:group permissions according to your settings in nginx.conf
In my case:
chown -R www-data:www-data /var/lib/phpmyadmin
Create a symlink to /srv/www/public or /var/www/html or wherever your server is looking for stuff.
You can add a second symlink named phpMyAdmin to phpmyadmin
Make sure that the root instruction in nginx.conf is set accordingly.
My nginx configuration is (nearly) identical on all my machines.
It is very compact right now.
To get started this is the easiest way. All further servers and features can be added later.
No entry in /etc/nginx/sites-enabled
and nothing in /etc/nginx/vhosts.d
Start with just one pool in php.ini. To configure that, google a litlle and test
by checking the status of php-fpm.
<?instead of<?php?<?). They are deprecated, don't really work in a lot of places, and are otherwise completely unneccessary. Saving three keystrokes is not a valid reason to allow potential for your code to fail on probably half of the servers it may run on.<?=), which should run fine on php 5.4+ regardless of server settings.tail -f -n 50 /var/log/apache2/error.loghelped me find the issue.
