Install gcc-8 only on Ubuntu 18.04?

I just installed Lubuntu 18.04 LTS. There are two options for installing gcc: gcc-7 and gcc-8. Both are available from apt-get install out of the box.
Even after I installed gcc-8, the system is still going to install gcc-7 when I install other packages such as build-essential.
Since gcc-8 is newer, is there a way to make it install gcc-8 and gcc-8 only?

gcc-7 is required by gcc-8. Note : You can have as many gcc/g++ versions as you want, installed at the same time. Bionic extras :g++-4.8 g++-5 g++-6 g++-8... ... g++-7/gcc-7 is the system compiler. The older versions are required for building some older applications.

gcc-7 and gcc-8 will happily co-live together.
I would suggest to let gcc-7 be installed, for satisfying build-essential and perhaps other dependent packages, and configure gcc-8 to be your default gcc installation.
Use update-alternatives for having gcc redirected automatically to gcc-8:
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 700 --slave /usr/bin/g++ g++ /usr/bin/g++-7
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-8 800 --slave /usr/bin/g++ g++ /usr/bin/g++-8
This will give you the convenience of gcc being at the latest version, and still you will be able to invoke gcc-7 or gcc-8 directly.
If you'll wish to change the default gcc version later on, run sudo update-alternatives --config gcc. It will bring a prompt similar to this, which lets you pick the version to be used:
There are 2 choices for the alternative gcc (providing /usr/bin/gcc).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/bin/gcc-8 800 auto mode
1 /usr/bin/gcc-7 700 manual mode
2 /usr/bin/gcc-8 800 manual mode
Press <enter> to keep the current choice[*], or type selection number:
The higher priority is the one that is picked automatically by update-alternatives.
