How could I increase the size of /tmp folder in AlmaLinux/CentOS?

[remics]

[root@]# df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 3.8G 0 3.8G 0% /dev tmpfs 3.8G 24M 3.8G 1% /dev/shm tmpfs 3.8G 377M 3.4G 10% /run /dev/sda2 291G 141G 136G 51% / /dev/sda3 2.9G 2.3G 455M 84% /tmp /dev/sda1 976M 240M 670M 27% /boot tmpfs 763M 0 763M 0% /run/user/0


[root@]# du -sh /tmp 2.3G /tmp

How could I do it, please?

umount it, resize, mount again.
better to do it booted from rescue-cd image.
