Reply To: I have problems with the installed plugin YITH WOOCOMMERCE CUSTOMIZE MY ACCOUNT

OK, you can hide our theme customization and keep only this plugin’s tabs adding this code snippet to the Custom CSS

.woocommerce-my-account-wrapper .woodmart-my-account-sidebar, 
.woocommerce-MyAccount-content .woodmart-my-account-links{
    display: none;
}

.woocommerce-my-account-wrapper .woocommerce-MyAccount-content{
    max-width: 100%;
}
